Merge tag 'statx-dioalign-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux
Pull STATX_DIOALIGN support from Eric Biggers: "Make statx() support reporting direct I/O (DIO) alignment information.
This provides a generic interface for userspace programs to determine whether a file supports DIO, and if so with what alignment restrictions. Specifically, STATX_DIOALIGN works on block devices, and on regular files when their containing filesystem has implemented support.
An interface like this has been requested for years, since the conditions for when DIO is supported in Linux have gotten increasingly complex over time. Today, DIO support and alignment requirements can be affected by various filesystem features such as multi-device support, data journalling, inline data, encryption, verity, compression, checkpoint disabling, log-structured mode, etc.
Further complicating things, Linux v6.0 relaxed the traditional rule of DIO needing to be aligned to the block device's logical block size; now user buffers (but not file offsets) only need to be aligned to the DMA alignment.
The approach of uplifting the XFS specific ioctl XFS_IOC_DIOINFO was discarded in favor of creating a clean new interface with statx().
For more information, see the individual commits and the man page update[1]"

ext4: fix i_version handling in ext4
ext4 currently updates the i_version counter when the atime is updated during a read. This is less than ideal as it can cause unnecessary cache invalidations with NFSv4 and unnecessary remeasurements for IMA.
The increment in ext4_mark_iloc_dirty is also problematic since it can corrupt the i_version counter for ea_inodes. We aren't bumping the file times in ext4_mark_iloc_dirty, so changing the i_version there seems wrong, and is the cause of both problems.
Remove that callsite and add increments to the setattr, setxattr and ioctl codepaths, at the same times that we update the ctime. The i_version bump that already happens during timestamp updates should take care of the rest.
In ext4_move_extents, increment the i_version on both inodes, and also add in missing ctime updates.
[ Some minor updates since we've already enabled the i_version counter unconditionally already via another patch series. -- TYT ]

ext4: place buffer head allocation before handle start
In our product environment, we encounter some jbd hung waiting handles to stop while several writters were doing memory reclaim for buffer head allocation in delay alloc write path. Ext4 do buffer head allocation with holding transaction handle which may be blocked too long if the reclaim works not so smooth. According to our bcc trace, the reclaim time in buffer head allocation can reach 258s and the jbd transaction commit also take almost the same time meanwhile. Except for these extreme cases, we often see several seconds delays for cgroup memory reclaim on our servers. This is more likely to happen considering docker environment.
One thing to note, the allocation of buffer heads is as often as page allocation or more often when blocksize less than page size. Just like page cache allocation, we should also place the buffer head allocation before startting the handle.

ext4: unconditionally enable the i_version counter
The original i_version implementation was pretty expensive, requiring a log flush on every change. Because of this, it was gated behind a mount option (implemented via the MS_I_VERSION mountoption flag).
Commit ae5e165d855d (fs: new API for handling inode->i_version) made the i_version flag much less expensive, so there is no longer a performance penalty from enabling it. xfs and btrfs already enable it unconditionally when the on-disk format can support it.
Have ext4 ignore the SB_I_VERSION flag, and just enable it unconditionally. While we're in here, mark the i_version mount option Opt_removed.
[ Removed leftover bits of i_version from ext4_apply_options() since it now can't ever be set in ctx->mask_s_flags -- lczerner ]

ext4: remove EA inode entry from mbcache on inode eviction
Currently we remove EA inode from mbcache as soon as its xattr refcount drops to zero. However there can be pending attempts to reuse the inode and thus refcount handling code has to handle the situation when refcount increases from zero anyway. So save some work and just keep EA inode in mbcache until it is getting evicted. At that moment we are sure following iget() of EA inode will fail anyway (or wait for eviction to finish and load things from the disk again) and so removing mbcache entry at that moment is fine and simplifies the code a bit.
