Merge tag 'afs-fixes-20190822' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Pull AFS fixes from David Howells:

 - Fix a cell record leak due to the default error not being cleared.

 - Fix an oops in tracepoint due to a pointer that may contain an error.

 - Fix the ACL storage op for YFS where the wrong op definition is being
   used. By luck, this only actually affects the information appearing
   in traces.

* tag 'afs-fixes-20190822' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs:
  afs: use correct afs_call_type in yfs_fs_store_opaque_acl2
  afs: Fix possible oops in afs_lookup trace event
  afs: Fix leak in afs_lookup_cell_rcu()
