Revert "lib/test_sort.c: make it explicitly non-modular"
Patch series "lib: add module support to sort tests".
This patch series allows to compile the array-based and linked list sort
test code either to loadable modules, or builtin into the kernel.
It's very valuable to have modular tests, so you can run them just by
insmodding the test modules, instead of needing a separate kernel that
runs them at boot.
This patch (of 3):

do_proc_dointvec_jiffies_conv() uses LONG_MAX/HZ as the max value to avoid overflow. But actually the *valp is int type, so it still causes overflow. For example, echo 2147483647 > ./sys/net/ipv4/tcp_keepalive_time Then, cat ./sys/net/ipv4/tcp_keepalive_time The output is "-1", it is not expected.

mm, compaction: finish whole pageblock to reduce fragmentation
The main goal of direct compaction is to form a high-order page for allocation, but it should also help against long-term fragmentation when possible. Most lower-than-pageblock-order compactions are for non-movable allocations, which means that if we compact in a movable pageblock and terminate as soon as we create the high-order page, it's unlikely that the fallback heuristics will claim the whole block. Instead there might be a single unmovable page in a pageblock full of movable pages, and the next unmovable allocation might pick another pageblock and increase long-term fragmentation. To help against such scenarios, this patch changes the termination criteria for compaction so that the current pageblock is finished even though the high-order page already exists. Note that it might be possible that the high-order page formed elsewhere in the zone due to parallel activity, but this patch doesn't try to detect that. This is only done with sync compaction, because async compaction is limited to pageblock of the same migratetype, where it cannot result in a migratetype fallback. (Async compaction also eagerly skips order-aligned blocks where isolation fails, which is against the goal of migrating away as much of the pageblock as possible.) As a result of this patch, long-term memory fragmentation should be reduced. In testing based on 4.9 kernel with stress-highalloc from mmtests configured for order-4 GFP_KERNEL allocations, this patch has reduced the number of unmovable allocations falling back to movable pageblocks by 20%.

mm, compaction: restrict async compaction to pageblocks of same migratetype
The migrate scanner in async compaction is currently limited to MIGRATE_MOVABLE pageblocks. This is a heuristic intended to reduce latency, based on the assumption that non-MOVABLE pageblocks are unlikely to contain movable pages. However, with the exception of THP's, most high-order allocations are not movable. Should the async compaction succeed, this increases the chance that the non-MOVABLE allocations will fallback to a MOVABLE pageblock, making the long-term fragmentation worse. This patch attempts to help the situation by changing async direct compaction so that the migrate scanner only scans the pageblocks of the requested migratetype. If it's a non-MOVABLE type and there are such pageblocks that do contain movable pages, chances are that the allocation can succeed within one of such pageblocks, removing the need for a fallback. If that fails, the subsequent sync attempt will ignore this restriction. In testing based on 4.9 kernel with stress-highalloc from mmtests configured for order-4 GFP_KERNEL allocations, this patch has reduced the number of unmovable allocations falling back to movable pageblocks by 30%. The number of movable allocations falling back is reduced by 12%.

mm, page_alloc: count movable pages when stealing from pageblock
When stealing pages from pageblock of a different migratetype, we count how many free pages were stolen, and change the pageblock's migratetype if more than half of the pageblock was free. This might be too conservative, as there might be other pages that are not free, but were allocated with the same migratetype as our allocation requested. While we cannot determine the migratetype of allocated pages precisely (at least without the page_owner functionality enabled), we can count pages that compaction would try to isolate for migration - those are either on LRU or __PageMovable(). The rest can be assumed to be MIGRATE_RECLAIMABLE or MIGRATE_UNMOVABLE, which we cannot easily distinguish. This counting can be done as part of free page stealing with little additional overhead. The page stealing code is changed so that it considers free pages plus pages of the "good" migratetype for the decision whether to change pageblock's migratetype. The result should be more accurate migratetype of pageblocks wrt the actual pages in the pageblocks, when stealing from semi-occupied pageblocks. This should help the efficiency of page grouping by mobility. In testing based on 4.9 kernel with stress-highalloc from mmtests configured for order-4 GFP_KERNEL allocations, this patch has reduced the number of unmovable allocations falling back to movable pageblocks by 47%. The number of movable allocations falling back to other pageblocks are increased by 55%, but these events don't cause permanent fragmentation, so the tradeoff should be positive. Later patches also offset the movable fallback increase to some extent.

mm, page_alloc: split smallest stolen page in fallback
The __rmqueue_fallback() function is called when there's no free page of requested migratetype, and we need to steal from a different one. There are various heuristics to make this event infrequent and reduce permanent fragmentation. The main one is to try stealing from a pageblock that has the most free pages, and possibly steal them all at once and convert the whole pageblock. Precise searching for such pageblock would be expensive, so instead the heuristics walks the free lists from MAX_ORDER down to requested order and assumes that the block with highest-order free page is likely to also have the most free pages in total. Chances are that together with the highest-order page, we steal also pages of lower orders from the same block. But then we still split the highest order page. This is wasteful and can contribute to fragmentation instead of avoiding it. This patch thus changes __rmqueue_fallback() to just steal the page(s) and put them on the freelist of the requested migratetype, and only report whether it was successful. Then we pick (and eventually split) the smallest page with __rmqueue_smallest(). This all happens under zone lock, so nobody can steal it from us in the process. This should reduce fragmentation due to fallbacks. At worst we are only stealing a single highest-order page and waste some cycles by moving it between lists and then removing it, but fallback is not exactly hot path so that should not be a concern. As a side benefit the patch removes some duplicate code by reusing __rmqueue_smallest().

mm, compaction: remove redundant watermark check in compact_finished()
When detecting whether compaction has succeeded in forming a high-order page, __compact_finished() employs a watermark check, followed by an own search for a suitable page in the freelists. This is not ideal for two reasons: - The watermark check also searches high-order freelists, but has a less strict criteria wrt fallback. It's therefore redundant and waste of cycles. This was different in the past when high-order watermark check attempted to apply reserves to high-order pages. - The watermark check might actually fail due to lack of order-0 pages. Compaction can't help with that, so there's no point in continuing because of that. It's possible that high-order page still exists and it terminates. This patch therefore removes the watermark check. This should save some cycles and terminate compaction sooner in some cases.

mm, compaction: reorder fields in struct compact_control
Patch series "try to reduce fragmenting fallbacks", v3.
Last year, Johannes Weiner has reported a regression in page mobility
grouping [1] and while the exact cause was not found, I've come up with
some ways to improve it by reducing the number of allocations falling
back to different migratetype and causing permanent fragmentation.
The series was tested with mmtests stress-highalloc modified to do
GFP_KERNEL order-4 allocations, on 4.9 with "mm, vmscan: fix zone
balance check in prepare_kswapd_sleep" (without that, kcompactd indeed
wasn't woken up) on UMA machine with 4GB memory. There were 5 repeats
of each run, as the extfrag stats are quite volatile (note the stats
below are sums, not averages, as it was less perl hacking for me).
Success rate are the same, already high due to the low allocation order
used, so I'm not including them.
Compaction stats:

Now kref.h is GPLv2 licensed, so any non-GPL code using it better be talking to some lawyers, but changing api markings isn't considered "nice", so let's fix this up.

libnvdimm for 4.12
* Region media error reporting: A libnvdimm region device is the parent to one or more namespaces. To date, media errors have been reported via the "badblocks" attribute attached to pmem block devices for namespaces in "raw" or "memory" mode. Given that namespaces can be in "device-dax" or "btt-sector" mode this new interface reports media errors generically, i.e. independent of namespace modes or state. This subsequently allows userspace tooling to craft "ACPI 6.1 Section 9.20.7.6 Function Index 4 - Clear Uncorrectable Error" requests and submit them via the ioctl path for NVDIMM root bus devices. * Introduce 'struct dax_device' and 'struct dax_operations': Prompted by a request from Linus and feedback from Christoph this allows for dax capable drivers to publish their own custom dax operations. This fixes the broken assumption that all dax operations are related to a persistent memory device, and makes it easier for other architectures and platforms to add customized persistent memory support. * 'libnvdimm' core updates: A new "deep_flush" sysfs attribute is available for storage appliance applications to manually trigger memory controllers to drain write-pending buffers that would otherwise be flushed automatically by the platform ADR (asynchronous-DRAM-refresh) mechanism at a power loss event. Support for "locked" DIMMs is included to prevent namespaces from surfacing when the namespace label data area is locked. Finally, fixes for various reported deadlocks and crashes, also tagged for -stable. * ACPI / nfit driver updates: General updates of the nfit driver to add DSM command overrides, ACPI 6.1 health state flags support, DSM payload debug available by default, and various fixes. Acknowledgements that came after the branch was pushed: commmit |

Staging/IIO patches for 4.12-rc1
Here is the big staging tree update for 4.12-rc1. And it's a big one, adding about 350k new lines of crap^Wcode, mostly all in a big dump of media drivers from Intel. But there's other new drivers in here as well, yet-another-wifi driver, new IIO drivers, and a new crypto accelerator. We also deleted a bunch of stuff, mostly in patch cleanups, but also the Android ION code has shrunk a lot, and the Android low memory killer driver was finally deleted, much to the celebration of the -mm developers. All of these have been in linux-next with a few build issues that will show up when you merge to your tree, I'll follow up with fixes for those after this gets merged.

We've got ten GFS2 patches for this merge window.
1. Andreas Gruenbacher wrote a patch to replace the deprecated call to rhashtable_walk_init with rhashtable_walk_enter. 2. Andreas also wrote a patch to eliminate redundant code in two of our debugfs sequence files. 3. Andreas also cleaned up the rhashtable key ugliness Linus pointed out during this cycle, following Linus's suggestions. 4. Andreas also wrote a patch to take advantage of his new function rhashtable_lookup_get_insert_fast. This makes glock lookup faster and more bullet-proof. 5. Andreas also wrote a patch to revert a patch in the evict path that caused occasional deadlocks, and is no longer needed. 6. Andrew Price wrote a patch to re-enable fallocate for the rindex system file to enable gfs2_grow to grow properly on secondary file system grow operations. 7. I wrote a patch to initialize an inode number field to make certain kernel trace points more understandable. 8. I also wrote a patch that makes GFS2 file system "withdraw" work more like it should by ignoring operations after a withdraw that would formerly cause a BUG() and kernel panic. 9. I also reworked the entire truncate/delete algorithm, scrapping the old recursive algorithm in favor of a new non-recursive algorithm. This was done for performance: This way, GFS2 no longer needs to lock multiple resource groups while doing truncates and deletes of files that cross multiple resource group boundaries, allowing for better parallelism. It also solves a problem whereby deleting large files would request a large chunk of kernel memory, which resulted in a get_page_from_freelist warning. 10. Due to a regression found during testing, I added a new patch to correct "GFS2: Prevent BUG from occurring when normal Withdraws occur". -----BEGIN PGP SIGNATURE----- iQEcBAABAgAGBQJZDNnaAAoJENeLYdPf93o7B7kIAJzwz7vVDVg2TpWVhMmXIWhf rZx3Gth5F0h+ZHddW7HzTLg+64XQ5//GyDD3UDtCpkhl5SJH+nt3juHyPJlRwioT 0ua4SjyKLQSoJJVAEgAwu42QjORTXab7NjYn5LEhvRc0Gg/El9WGU+ZgmP2/aAvf KE2u/IEYNDkoJNS3Oqc7shajAyLYda6wCAASs/1ZGt9u48m/o/I23Zd7wr7EOkzw rd3gB0x80cJqDAB5IcymGOm111Tg4g34LwsRuyMnWE3H1jOgV+J515FVHEIvZuPq Wl9X7V8CzktI7nyLKVnZhpuv5JzyMq/vOPiD01tTFx8Oy1JCRezjmATXFjW/zIo= =MX3c -----END PGP SIGNATURE----- Merge tag 'gfs2-4.12.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2 Pull GFS2 updates from Bob Peterson: "We've got ten GFS2 patches for this merge window. - Andreas Gruenbacher wrote a patch to replace the deprecated call to rhashtable_walk_init with rhashtable_walk_enter. - Andreas also wrote a patch to eliminate redundant code in two of our debugfs sequence files. - Andreas also cleaned up the rhashtable key ugliness Linus pointed out during this cycle, following Linus's suggestions. - Andreas also wrote a patch to take advantage of his new function rhashtable_lookup_get_insert_fast.

Some cleanups:
remove unused get_fsid_from_ino fix bounds check for listxattr clean up oversize xattr validation do not set getattr_time on orangefs_lookup return from orangefs_devreq_read quickly if possible do not wait for timeout if umounting handle zero size write in debugfs Bug fixes: do not check possibly stale size on truncate ensure the userspace component is unmounted if mount fails total reimplementation of dir.c New feature: implement statx The new implementation of dir.c is kind of a big deal, all new code.

powerpc updates for 4.12 part 1.
Highlights include: - Larger virtual address space on 64-bit server CPUs. By default we use a 128TB virtual address space, but a process can request access to the full 512TB by passing a hint to mmap(). - Support for the new Power9 "XIVE" interrupt controller. - TLB flushing optimisations for the radix MMU on Power9. - Support for CAPI cards on Power9, using the "Coherent Accelerator Interface Architecture 2.0". - The ability to configure the mmap randomisation limits at build and runtime. - Several small fixes and cleanups to the kprobes code, as well as support for KPROBES_ON_FTRACE. - Major improvements to handling of system reset interrupts, correctly treating them as NMIs, giving them a dedicated stack and using a new hypervisor call to trigger them, all of which should aid debugging and robustness. Many fixes and other minor enhancements.
