> - Numerous corruption fixes for blocksize < pagesize writes
> - Don't miscalculate AG reservations for small final AGs
> - Fix page cache truncation to work properly for reflink and extent
> shifting
> - Fix use-after-free when retrying failed inode/dquot buffer logging
> - Fix corruptions seen when using copy_file_range in directio mode
>
> ----------------------------------------------------------------
> Brian Foster (1):
> xfs: fix shared extent data corruption due to missing cow reservation
>
> Dave Chinner (11):
> xfs: uncached buffer tracing needs to print bno
> xfs: fix transient reference count error in xfs_buf_resubmit_failed_buffers
> xfs: finobt AG reserves don't consider last AG can be a runt
> xfs: extent shifting doesn't fully invalidate page cache
> xfs: flush removing page cache in xfs_reflink_remap_prep
> xfs: delalloc -> unwritten COW fork allocation can go wrong
> iomap: FUA is wrong for DIO O_DSYNC writes into unwritten extents
> iomap: sub-block dio needs to zeroout beyond EOF
> iomap: dio data corruption and spurious errors when pipes fill
> vfs: vfs_dedupe_file_range() doesn't return EOPNOTSUPP
> iomap: readpages doesn't zero page tail beyond EOF
