One of the goals is to reduce the overhead of using ->read_iter()
and ->write_iter() instead of ->read()/->write(); new_sync_{read,write}()
has a surprising amount of overhead, in particular inside iocb_flags().
That's why the beginning of the series is in this pile; it's not directly
iov_iter-related, but it's a part of the same work...

Pull io_uring buffered writes support from Jens Axboe:
"This contains support for buffered writes, specifically for XFS. btrfs
is in progress, will be coming in the next release.
io_uring does support buffered writes on any file type, but since the
buffered write path just always -EAGAIN (or -EOPNOTSUPP) any attempt
to do so if IOCB_NOWAIT is set, any buffered write will effectively be
handled by io-wq offload. This isn't very efficient, and we even have
specific code in io-wq to serialize buffered writes to the same inode
to avoid further inefficiencies with thread offload.
This is particularly sad since most buffered writes don't block, they
simply copy data to a page and dirty it. With this pull request, we
can handle buffered writes a lot more effiently.
If balance_dirty_pages() needs to block, we back off on writes as
indicated.
This improves buffered write support by 2-3x.
Jan Kara helped with the mm bits for this, and Stefan handled the
fs/iomap/xfs/io_uring parts of it"

Pull io_uring updates from Jens Axboe:
- As per (valid) complaint in the last merge window, fs/io_uring.c has
grown quite large these days. io_uring isn't really tied to fs
either, as it supports a wide variety of functionality outside of
that.
Move the code to io_uring/ and split it into files that either
implement a specific request type, and split some code into helpers
as well. The code is organized a lot better like this, and io_uring.c
is now < 4K LOC (me).
- Deprecate the epoll_ctl opcode. It'll still work, just trigger a
warning once if used. If we don't get any complaints on this, and I
don't expect any, then we can fully remove it in a future release
(me).
- Improve the cancel hash locking (Hao)
- kbuf cleanups (Hao)
- Efficiency improvements to the task_work handling (Dylan, Pavel)
- Provided buffer improvements (Dylan)
- Add support for recv/recvmsg multishot support. This is similar to
the accept (or poll) support for have for multishot, where a single
SQE can trigger everytime data is received. For applications that
expect to do more than a few receives on an instantiated socket, this
greatly improves efficiency (Dylan).
- Efficiency improvements for poll handling (Pavel)
- Poll cancelation improvements (Pavel)
- Allow specifiying a range for direct descriptor allocations (Pavel)
- Cleanup the cqe32 handling (Pavel)
- Move io_uring types to greatly cleanup the tracing (Pavel)
- Tons of great code cleanups and improvements (Pavel)
- Add a way to do sync cancelations rather than through the sqe -> cqe
interface, as that's a lot easier to use for some use cases (me).
- Add support to IORING_OP_MSG_RING for sending direct descriptors to a
different ring. This avoids the usually problematic SCM case, as we
disallow those. (me)
- Make the per-command alloc cache we use for apoll generic, place
limits on it, and use it for netmsg as well (me).

Pull acl updates from Christian Brauner:
"Last cycle we introduced support for mounting overlayfs on top of
idmapped mounts. While looking into additional testing we realized
that posix acls don't really work correctly with stacking filesystems
on top of idmapped layers.
We already knew what the fix were but it would require work that is
more suitable for the merge window so we turned off posix acls for
v5.19 for overlayfs on top of idmapped layers with Miklos routing my
patch upstream in 72a8e05d4f ("Merge tag 'ovl-fixes-5.19-rc7' [..]").
This contains the work to support posix acls for overlayfs on top of
idmapped layers. Since the posix acl fixes should use the new
vfs{g,u}id_t work the associated branch has been merged in. (We sent a
pull request for this earlier.)
We've also pulled in Miklos pull request containing my patch to turn
of posix acls on top of idmapped layers. This allowed us to avoid
rebasing the branch which we didn't like because we were already at
rc7 by then. Merging it in allows this branch to first fix posix acls
and then to cleanly revert the temporary fix it brought in by commit
4a47c6385b ("ovl: turn of SB_POSIXACL with idmapped layers
temporarily").
The last patch in this series adds Seth Forshee as a co-maintainer for
idmapped mounts. Seth has been integral to all of this work and is
also the main architect behind the filesystem idmapping work which
ultimately made filesystems such as FUSE and overlayfs available in
containers. He continues to be active in both development and review.
I'm very happy he decided to help and he has my full trust. This
increases the bus factor which is always great for work like this. I'm
honestly very excited about this because I think in general we don't
do great in the bringing on new maintainers department"

Merge tag 'fs.idmapped.vfsuid.v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull fs idmapping updates from Christian Brauner:
"This introduces the new vfs{g,u}id_t types we agreed on. Similar to
k{g,u}id_t the new types are just simple wrapper structs around
regular {g,u}id_t types.
They allow to establish a type safety boundary in the VFS for idmapped
mounts preventing confusion betwen {g,u}ids mapped into an idmapped
mount and {g,u}ids mapped into the caller's or the filesystem's
idmapping.
An initial set of helpers is introduced that allows to operate on
vfs{g,u}id_t types. We will remove all references to non-type safe
idmapped mounts helpers in the very near future. The patches do
already exist.
This converts the core attribute changing codepaths which become
significantly easier to reason about because of this change.
Just a few highlights here as the patches give detailed overviews of
what is happening in the commit messages:
- The kernel internal struct iattr contains type safe vfs{g,u}id_t
values clearly communicating that these values have to take a given
mount's idmapping into account.
- The ownership values placed in struct iattr to change ownership are
identical for idmapped and non-idmapped mounts going forward. This
also allows to simplify stacking filesystems such as overlayfs that
change attributes In other words, they always represent the values.
- Instead of open coding checks for whether ownership changes have
been requested and an actual update of the inode is required we now
have small static inline wrappers that abstract this logic away
removing a lot of code duplication from individual filesystems that
all open-coded the same checks"

"A fix for ext2 handling of a corrupted fs image and cleanups in ext2
and reiserfs"
* tag 'fs_for_v5.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
ext2: Add more validity checks for inode counts
fs/reiserfs/inode: remove dead code in _get_block_create_0()
fs/ext2: replace ternary operator with min_t()
Changes in this set of commits:
. Delay the cleanup of interrupted posix lock requests until the
user space result arrives. Previously, the immediate cleanup
would lead to extraneous warnings when the result arrived.
. Tracepoint improvements, e.g. adding the lock resource name.
. Delay the completion of lockspace creation until one full recovery
cycle has completed. This allows more error cases to be returned to
the caller.
. Remove warnings from the locking layer about delayed network replies.
The recently added midcomms warnings are much more useful.
. Begin the process of deprecating two unused lock-timeout-related
features. These features now require enabling via a Kconfig option,
and enabling them triggers deprecation warnings. We expect to
remove the code in v6.2.

The unhold_lkb() function decrements the lock's kref, and
asserts that the ref count was not the final one. Use the
kref_put release function (which should not be called) to
call the assert, rather than doing the assert based on the
kref_put return value. Using kill_lkb() as the release
function doesn't make sense if we only want to assert.

This patch will disable use of deprecated timeout features if
CONFIG_DLM_DEPRECATED_API is not set. The deprecated features
will be removed in upcoming kernel release v6.2.

This patch adds a CONFIG_DLM_DEPRECATED_API Kconfig option
that must be enabled to use two timeout-related features
that we intend to remove in kernel v6.2. Warnings are
printed if either is enabled and used. Neither has ever
been used as far as we know.
. The DLM_LSFL_TIMEWARN lockspace creation flag will be
removed, along with the associated configfs entry for
setting the timeout. Setting the flag and configfs file
would cause dlm to track how long locks were waiting
for reply messages. After a timeout, a kernel message
would be logged, and a netlink message would be sent
to userspace. Recently, midcomms messages have been
added that produce much better logging about actual
problems with messages. No use has ever been found
for the netlink messages.
. The userspace libdlm API has allowed the DLM_LKF_TIMEOUT
flag with a timeout value to be set in lock requests.
The lock request would be cancelled after the timeout.
