Merge tag 'ceph-for-4.10-rc1' of git://github.com/ceph/ceph-client
Pull ceph updates from Ilya Dryomov: "A varied set of changes: - a large rework of cephx auth code to cope with CONFIG_VMAP_STACK (myself). Also fixed a deadlock caused by a bogus allocation on the writeback path and authorize reply verification. - a fix for long stalls during fsync (Jeff Layton). The client now has a way to force the MDS log flush, leading to ~100x speedups in some synthetic tests. - a new [no]require_active_mds mount option (Zheng Yan). On mount, we will now check whether any of the MDSes are available and bail rather than block if none are. This check can be avoided by specifying the "no" option. - a couple of MDS cap handling fixes and a few assorted patches throughout" * tag 'ceph-for-4.10-rc1' of git://github.com/ceph/ceph-client: (32 commits) libceph: remove now unused finish_request() wrapper libceph: always signal completion when done ceph: avoid creating orphan object when checking pool permission ceph: properly set issue_seq for cap release ceph: add flags parameter to send_cap_msg ceph: update cap message struct version to 10 ceph: define new argument structure for send_cap_msg ceph: move xattr initialzation before the encoding past the ceph_mds_caps ceph: fix minor typo in unsafe_request_wait ceph: record truncate size/seq for snap data writeback ceph: check availability of mds cluster on mount ceph: fix splice read for no Fc capability case ceph: try getting buffer capability for readahead/fadvise ceph: fix scheduler warning due to nested blocking ceph: fix printing wrong return variable in ceph_direct_read_write() crush: include mapper.h in mapper.c rbd: silence bogus -Wmaybe-uninitialized warning libceph: no need to drop con->mutex for ->get_authorizer() libceph: drop len argument of *verify_authorizer_reply() libceph: verify authorize reply on connect ...
