  rbd: flush rbd_dev->watch_dwork after watch is unregistered (2018-06-04 20:46:02 +0200)

----------------------------------------------------------------
The main piece is a set of libceph changes that revamps how OSD
requests are aborted, improving CephFS ENOSPC handling and making
"umount -f" actually work (Zheng and myself).  The rest is mostly
mount option handling cleanups from Chengguang and assorted fixes
from Zheng, Luis and Dongsheng.

----------------------------------------------------------------
Chengguang Xu (5):
      libceph, rbd: add error handling for osd_req_op_cls_init()
      ceph: fix alignment of rasize
      ceph: strengthen rsize/wsize/readdir_max_bytes validation
      ceph: show ino32 if the value is different with default
      ceph: update description of some mount options

Dongsheng Yang (1):
      rbd: flush rbd_dev->watch_dwork after watch is unregistered

Ilya Dryomov (13):
      libceph: get rid of more_kvec in try_write()

      libceph: introduce ceph_osdc_abort_requests()
      libceph: no need to call flush_workqueue() before destruction
      libceph: move more code into __complete_request()
      libceph: defer __complete_request() to a workqueue
      libceph: use for_each_request() in ceph_osdc_abort_on_full()
      libceph: don't warn if req->r_abort_on_full is set
      libceph: avoid a use-after-free during map check
      libceph: don't abort reads in ceph_osdc_abort_on_full()
      libceph: make abort_on_full a per-osdc setting
      libceph: allocate the locator string with GFP_NOFAIL

Luis Henriques (2):
      ceph: fix st_nlink stat for directories
      ceph: fix use-after-free in ceph_statfs()

Yan, Zheng (10):
      ceph: use bit flags to define vxattr attributes
      ceph: always get rstat from auth mds
      ceph: update i_files/i_subdirs only when Fs cap is issued
