  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_snap_context.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()
      rbd: move rbd_unregister_watch() call into rbd_dev_image_release()
      rbd: fix error handling around rbd_init_disk()
      rbd: ignore unlock errors
      rbd: store lock cookie
      rbd: support updating the lock cookie without releasing the lock
      rbd: kill rbd_is_lock_supported()
      rbd: return ResponseMessage result from rbd_handle_request_lock()
      rbd: exclusive map option

Jeff Layton (7):
      libceph: remove req->r_replay_version
      libceph: allow requests to return immediately on full conditions if caller wishes
      libceph: abort already submitted but abortable requests when map or pool goes full
      libceph: add an epoch_barrier field to struct ceph_osd_client
      ceph: handle epoch barriers in cap messages
      Revert "ceph: SetPageError() for writeback pages if writepages fails"
      ceph: when seeing write errors on an inode, switch to sync writes

Luis Henriques (1):
      ceph: fix memory leak in __ceph_setxattr()

Yan, Zheng (6):
      ceph: fix wrong check in ceph_renew_caps()
      ceph: allow connecting to mds whose rank >= mdsmap::m_max_mds
      ceph: fix potential use-after-free
      ceph: close stopped mds' session
      ceph: make seeky readdir more efficient
      ceph: choose readdir frag based on previous readdir reply
