Merge tag 'misc-fixes-20211007' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull netfslib, cachefiles and afs fixes from David Howells:
- Fix another couple of oopses in cachefiles tracing stemming from the
possibility of passing in a NULL object pointer
- Fix netfs_clear_unread() to set READ on the iov_iter so that source
it is passed to doesn't do the wrong thing (some drivers look at the
flag on iov_iter rather than other available information to determine
the direction)
- Fix afs_launder_page() to write back at the correct file position on
the server so as not to corrupt data
* tag 'misc-fixes-20211007' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs:
afs: Fix afs_launder_page() to set correct start file position
netfs: Fix READ/WRITE confusion when calling iov_iter_xarray()
cachefiles: Fix oops with cachefiles_cull() due to NULL object
