Merge tag 'fscache-fixes-20200508-2' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
(1) The reorganisation of bmap() use accidentally caused the return value of cachefiles_read_or_alloc_pages() to get corrupted. (2) The NFS superblock index key accidentally got changed to include a number of kernel pointers - meaning that the key isn't matchable after a reboot. (3) A redundant check in nfs_fscache_get_super_cookie(). (4) The NFS change_attr sometimes set in the auxiliary data for the caching of an file and sometimes not, which causes the cache to get discarded when it shouldn't. (5) There's a race between cachefiles_read_waiter() and cachefiles_read_copier() that causes an occasional assertion failure.
