  fs: clean up after mandatory file locking support removal (2021-08-24 07:52:45 -0400)

----------------------------------------------------------------
Hi Linus,

Sending this along early as I don't expect it to change between now and
when the merge window opens.

This PR starts with a couple of fixes for potential deadlocks in the
fowner/fasync handling. The next patch removes the old mandatory locking
code from the kernel altogether. The last patch cleans up rw_verify_area
a bit more after the mandatory locking removal.

Thanks!
