a6d3a479ae f2fs: record quota during dot{,dot} recovery
In ->lookup(), we will have a try to recover dot or dotdot for
corrupted directory, once disk quota is on, if it allocates new
block during dotdot recovery, we need to record disk quota info
for the allocation, so this patch fixes this issue by adding
missing dquot_initialize() in __recover_dot_dentries.

7a2af766af f2fs: enhance on-disk inode structure scalability
This patch add new flag F2FS_EXTRA_ATTR storing in inode.i_inline
to indicate that on-disk structure of current inode is extended.

In order to extend, we changed the inode structure a bit:

Original one:

struct f2fs_inode {
	...
	struct f2fs_extent i_ext;
	__le32 i_addr[DEF_ADDRS_PER_INODE];
	__le32 i_nid[DEF_NIDS_PER_INODE];
}

Extended one:

struct f2fs_inode {
        ...
        struct f2fs_extent i_ext;
	union {
		struct {
			__le16 i_extra_isize;
			__le16 i_padding;
			__le32 i_extra_end[0];
		};
		__le32 i_addr[DEF_ADDRS_PER_INODE];
	};
        __le32 i_nid[DEF_NIDS_PER_INODE];
}

Once F2FS_EXTRA_ATTR is set, we will steal four bytes in the head of
i_addr field for storing i_extra_isize and i_padding. with i_extra_isize,
we can calculate actual size of reserved space in i_addr, available
attribute fields included in total extra attribute fields for current
inode can be described as below:

  +--------------------+
  | .i_mode            |
  | ...                |
  | .i_ext             |
  +--------------------+
  | .i_extra_isize     |-----+
  | .i_padding         |     |
  | .i_prjid           |     |
  | .i_atime_extra     |     |
  | .i_ctime_extra     |     |
  | .i_mtime_extra     |<----+
  | .i_inode_cs        |<----- store blkaddr/inline from here
  | .i_xattr_cs        |
  | ...                |
  +--------------------+
  |                    |
  |    block address   |
  |                    |
  +--------------------+
  | .i_nid             |
  +--------------------+
  |   node_footer      |
  | (nid, ino, offset) |
  +--------------------+

Hence, with this patch, we would enhance scalability of f2fs inode for
storing more newly added attribute.

f247037120 f2fs: make max inline size changeable
This patch tries to make below macros calculating max inline size,
inline dentry field size considerring reserving size-changeable
space:
- MAX_INLINE_DATA
- NR_INLINE_DENTRY
- INLINE_DENTRY_BITMAP_SIZE
- INLINE_RESERVED_SIZE

Then, when inline_{data,dentry} options is enabled, it allows us to
reserve inline space with different size flexibly for adding newly
introduced inode attribute.

dc6febb6bc f2fs: make background threads of f2fs being aware of freezing
When ->freeze_fs is called from lvm for doing snapshot, it needs to
make sure there will be no more changes in filesystem's data, however,
previously, background threads like GC thread wasn't aware of freezing,
so in environment with active background threads, data of snapshot
becomes unstable.

This patch fixes this issue by adding sb_{start,end}_intwrite in
below background threads:
- GC thread
- flush thread
- discard thread

Note that, don't use sb_start_intwrite() in gc_thread_func() due to:

7a10f0177e f2fs: don't give partially written atomic data from process crash
This patch resolves the below scenario.

== Process 1 ==     == Process 2 ==
open(w)             open(rw)
begin
write(new_#1)
process_crash
  f_op->flush
  locks_remove_posix
  f_op>release
                    read (new_#1)

In order to avoid corrupted database caused by new_#1, we must do roll-back
at process_crash time. In order to check that, this patch keeps task which
triggers transaction begin, and does roll-back in f_op->flush before removing
file locks.

14af20fcb1 f2fs: preserve i_mode if __f2fs_set_acl() fails
When changing a file's acl mask, __f2fs_set_acl() will first set the
group bits of i_mode to the value of the mask, and only then set the
actual extended attribute representing the new acl.

If the second part fails (due to lack of space, for example) and the
file had no acl attribute to begin with, the system will from now on
assume that the mask permission bits are actual group permission bits,
potentially granting access to the wrong users.

Prevent this by only changing the inode mode after the acl has been set.

fd2b2c57ec SCSI fixes on 20170725
Three small fixes.  The transfer size fixes are actually correcting
 some performance drops on the hpsa and smartpqi cards.  The cards
 actually have an internal cache for request speed up but bypass it for
 transfers > 1MB.  Since 4.3 the efficiency of our merges has rendered
 the cache mostly unused, so limit transfers to under 1MB to recover
 the cache boost.

7683e9e529 Properly alphabetize MAINTAINERS file
This adds a perl script to actually parse the MAINTAINERS file, clean up
some whitespace in it, warn about errors in it, and then properly sort
the end result.

My perl-fu is atrocious, so the script has basically been created by
randomly putting various characters in a pile, mixing them around, and
then looking it the end result does anything interesting when used as a
perl script.

f47e07bc5f Fix up MAINTAINERS file problems
Prepping for scripting the MAINTAINERS file cleanup (and possible split)
showed a couple of cases where the headers for a couple of entries were
bogus.

There's a few different kinds of bogosities:

 - the X-GENE SOC EDAC case was confused and split over two lines

 - there were four entries for "GREYBUS PROTOCOLS DRIVERS" that were all
   different things.

 - the NOKIA N900 CAMERA SUPPORT" was duplicated

all of which were more obvious when you started doing associative arrays
in perl to track these things by the header (so that we can alphabetize
this thing properly, and so that we might split it up by the data too).

96edd61dcf xen/balloon: don't online new memory initially
When setting up the Xenstore watch for the memory target size the new
watch will fire at once. Don't try to reach the configured target size
by onlining new memory in this case, as the current memory size will
be smaller in almost all cases due to e.g. BIOS reserved pages.

Onlining new memory will lead to more problems e.g. undesired conflicts
with NVMe devices meant to be operated as block devices.

Instead remember the difference between target size and current size
when the watch fires for the first time and apply it to any further
size changes, too.

In order to avoid races between balloon.c and xen-balloon.c init calls
do the xen-balloon.c initialization from balloon.c.

Commit dc6416f1d7 ("xen/x86: Call
cpu_startup_entry(CPUHP_AP_ONLINE_IDLE) from xen_play_dead()")
introduced an error leading to a stack overflow of the idle task when
a cpu was brought offline/online many times: by calling
cpu_startup_entry() instead of returning at the end of xen_play_dead()
do_idle() would be entered again and again.

Don't use cpu_startup_entry(), but cpuhp_online_idle() instead allowing
to return from xen_play_dead().

Sometimes the lack of grants causes IO hangs in xen_blkfront devices.

Pull more rdma fixes from Doug Ledford:
 "As per my previous pull request, there were two drivers that each had
  a rather large number of legitimate fixes still to be sent.

  As it turned out, I also missed a reasonably large set of fixes from
  one person across the stack that are all important fixes. All in all,
  the bnxt_re, i40iw, and Dan Carpenter are 3/4 to 2/3rds of this pull
  request.

  There were some other random fixes that I didn't send in the last pull
  request that I added to this one. This catches the rdma stack up to
  the fixes from up to about the beginning of this week. Any more fixes
  I'll wait and batch up later in the -rc cycle. This will give us a
  good base to start with for basing a for-next branch on -rc2.

   - i40iw fixes

   - bnxt_re fixes

   - Dan Carpenter bugfixes across stack

10fc95547f powerpc fixes for 4.13 #3
A handful of fixes, mostly for new code.
 
 Some reworking of the new STRICT_KERNEL_RWX support to make sure we also remove
 executable permission from __init memory before it's freed.
 
 A fix to some recent optimisations to the hypercall entry where we were
 clobbering r12, this was breaking nested guests (PR KVM).
 
 A fix for the recent patch to opal_configure_cores(). This could break booting
 on bare metal Power8 boxes if the kernel was built without
 CONFIG_JUMP_LABEL_FEATURE_CHECK_DEBUG.
 
 And finally a workaround for spurious PMU interrupts on Power9 DD2.
