Merge tag 'ceph-for-4.14-rc1' of git://github.com/ceph/ceph-client
Pull ceph updates from Ilya Dryomov: "The highlights include: - a large series of fixes and improvements to the snapshot-handling code (Zheng Yan) - individual read/write OSD requests passed down to libceph are now limited to 16M in size to avoid hitting OSD-side limits (Zheng Yan) - encode MStatfs v2 message to allow for more accurate space usage reporting (Douglas Fuller) - switch to the new writeback error tracking infrastructure (Jeff Layton)" * tag 'ceph-for-4.14-rc1' of git://github.com/ceph/ceph-client: (35 commits) ceph: stop on-going cached readdir if mds revokes FILE_SHARED cap ceph: wait on writeback after writing snapshot data ceph: fix capsnap dirty pages accounting ceph: ignore wbc->range_{start,end} when write back snapshot data ceph: fix "range cyclic" mode writepages ceph: cleanup local variables in ceph_writepages_start() ceph: optimize pagevec iterating in ceph_writepages_start() ceph: make writepage_nounlock() invalidate page that beyonds EOF ceph: properly get capsnap's size in get_oldest_context() ceph: remove stale check in ceph_invalidatepage() ceph: queue cap snap only when snap realm's context changes ceph: handle race between vmtruncate and queuing cap snap ceph: fix message order check in handle_cap_export() ceph: fix NULL pointer dereference in ceph_flush_snaps() ceph: adjust 36 checks for NULL pointers ceph: delete an unnecessary return statement in update_dentry_lease() ceph: ENOMEM pr_err in __get_or_create_frag() is redundant ceph: check negative offsets in ceph_llseek() ceph: more accurate statfs ceph: properly set snap follows for cap reconnect ...
