Merge tag 'locks-v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux

Pull mandatory file locking deprecation warning from Jeff Layton:
"As discussed on the list, this patch just adds a new warning for folks
who still have mandatory locking enabled and actually mount with '-o
mand'. I'd like to get this in for v5.14 so we can push this out into
stable kernels and hopefully reach folks who have mounts with -o mand.

For now, I'm operating under the assumption that we'll fully remove
this support in v5.15, but we can move that out if any legitimate
users of this facility speak up between now and then"
