Pull file locking fixes from Jeff Layton: "Just a couple of late-breaking patches for the file locking code. The second patch (from yangerkun) fixes a rather nasty looking potential use-after-free that should go to stable. The other patch could technically wait for 5.7, but it's fairly innocuous so I figured we might as well take it" * tag 'filelock-v5.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux: locks: fix a potential use-after-free problem when wakeup a waiter fcntl: Distribute switch variables for initialization
