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. * tag 'ceph-for-4.18-rc1' of git://github.com/ceph/ceph-client: (31 commits) rbd: flush rbd_dev->watch_dwork after watch is unregistered ceph: update description of some mount options ceph: show ino32 if the value is different with default ceph: strengthen rsize/wsize/readdir_max_bytes validation ceph: fix alignment of rasize ceph: fix use-after-free in ceph_statfs() ceph: prevent i_version from going back ceph: fix wrong check for the case of updating link count libceph: allocate the locator string with GFP_NOFAIL libceph: make abort_on_full a per-osdc setting libceph: don't abort reads in ceph_osdc_abort_on_full() libceph: avoid a use-after-free during map check libceph: don't warn if req->r_abort_on_full is set libceph: use for_each_request() in ceph_osdc_abort_on_full() libceph: defer __complete_request() to a workqueue libceph: move more code into __complete_request() libceph: no need to call flush_workqueue() before destruction ceph: flush pending works before shutdown super ceph: abort osd requests on force umount libceph: introduce ceph_osdc_abort_requests() ...
