Merge tag 'locks-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux
Pull file locking updates from Jeff Layton:
"Most of this is just follow-on cleanup work of documentation and
comments from the mandatory locking removal in v5.15.
The only real functional change is that LOCK_MAND flock() support is
also being removed, as it has basically been non-functional since the
v2.5 days"
* tag 'locks-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux:
fs: remove leftover comments from mandatory locking removal
locks: remove changelog comments
docs: fs: locks.rst: update comment about mandatory file locking
Documentation: remove reference to now removed mandatory-locking doc
locks: remove LOCK_MAND flock lock support
