  libceph: allow addrvecs with a single NONE/blank address (2021-05-04 16:06:15 +0200)

There is a merge conflict in fs/ceph/dir.c because Jeff's inode
type handling patch went through the vfs tree together with Al's
inode_wrong_type() helper.  for-linus-merged has the resolution.

----------------------------------------------------------------
Notable items here are a series to take advantage of David Howells'
netfs helper library from Jeff, three new filesystem client metrics
from Xiubo, ceph.dir.rsnaps vxattr from Yanhu and two auth-related
fixes from myself, marked for stable.  Interspersed is a smattering
of assorted fixes and cleanups across the filesystem.
