Merge tag 'afs-cachefiles-fixes-20210323' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull cachefiles and afs fixes from David Howells:
"Fixes from Matthew Wilcox for page waiting-related issues in
cachefiles and afs as extracted from his folio series[1]:
- In cachefiles, remove the use of the wait_bit_key struct to access
something that's actually in wait_page_key format. The proper
struct is now available in the header, so that should be used
instead.
- Add a proper wait function for waiting killably on the page
writeback flag. This includes a recent bugfix[2] that's not in the
afs code.
- In afs, use the function added in (2) rather than using
wait_on_page_bit_killable() which doesn't provide the
aforementioned bugfix"
