Merge tag 'ceph-for-4.18-rc1' of git://github.com/ceph/ceph-client

Pull ceph updates from Ilya Dryomov:
 "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).

  assorted fixes from Zheng, Luis and Dongsheng.
