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).
The rest is mostly mount option handling cleanups from Chengguang and
assorted fixes from Zheng, Luis and Dongsheng.
