Hello Linus,
could you please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs.git hole_punch_for_v5.14-rc1
to get patches that fix races leading to possible data corruption or stale
data exposure in multiple filesystems when hole punching races with
operations such as readahead.
Top of the tree is e996ae6bdbd1. The full shortlog is:

mm: Fix comments mentioning i_mutex
documentation: Sync file_operations members with reality
mm: Protect operations adding pages to page cache with invalidate_lock
mm: Add functions to lock invalidate_lock for two mappings
ext4: Convert to use mapping->invalidate_lock
ext2: Convert to using invalidate_lock
xfs: Convert to use invalidate_lock
xfs: Convert double locking of MMAPLOCK to use VFS helpers
zonefs: Convert to using invalidate_lock
f2fs: Convert to using invalidate_lock
fuse: Convert to using invalidate_lock
ceph: Fix race between hole punch and page fault
cifs: Fix race between hole punch and page fault
Pavel Reichl (1):
