  ceph: fix memory leak in __ceph_setxattr() (2017-05-04 09:19:24 +0200)

----------------------------------------------------------------
The two main items are support for disabling automatic rbd exclusive
lock transfers from myself and the long awaited -ENOSPC handling series
from Jeff.  The former will allow rbd users to take advantage of
exclusive lock's built-in blacklist/break-lock functionality while
staying in control of who owns the lock.  With the latter in place, we
will abort filesystem writes on -ENOSPC instead of having them block
indefinitely.

Beyond that we've got the usual pile of filesystem fixes from Zheng,
some refcount_t conversion patches from Elena and a patch for an
ancient open() flags handling bug from Alexander.

----------------------------------------------------------------
Alexander Graf (1):
      ceph: fix file open flags on ppc64

Elena Reshetova (5):
      ceph: convert ceph_mds_session.s_ref from atomic_t to refcount_t
      ceph: convert ceph_cap_snap.nref from atomic_t to refcount_t

      libceph: convert ceph_osd.o_ref from atomic_t to refcount_t
      libceph: convert ceph_pagelist.refcnt from atomic_t to refcount_t

Ilya Dryomov (11):
      libceph, ceph: always advertise all supported features
      libceph: supported_features module parameter
      rbd: move rbd_dev_destroy() call out of rbd_dev_image_release()
