Subject[PATCH 0/4] cachefiles, nfs: Fixes
From
Date

Hi Linus, Trond, Anna,

Can you pull these fixes for cachefiles and NFS's use of fscache? Should
they go through the NFS tree or directly upstream? The things fixed are:

(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.

The patches are tagged here:

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git
tag fscache-fixes-20200508

Thanks,
David
