Merge branch 'keys-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull watch_queue fixes from David Howells:
"Here are fixes for a couple more watch_queue bugs, both found by syzbot:
- Fix error cleanup in watch_queue_set_size() where it tries to clean
up all the pointers in the page list, even if they've not been
allocated yet[1]. Unfortunately, __free_page() doesn't treat a NULL
pointer as being "do nothing".
A second report[2] looks like it's probably the same bug, but on
arm64 rather than x86_64, but there's no reproducer.
- Fix a missing kfree in free_watch() to actually free the watch[3]"
