Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client
Pull Ceph updates from Sage Weil: "There is the long-awaited discard support for RBD (Guangliang Zhao, Josh Durgin), a pile of RBD bug fixes that didn't belong in late -rc's (Ilya Dryomov, Li RongQing), a pile of fs/ceph bug fixes and performance and debugging improvements (Yan, Zheng, John Spray), and a smattering of cleanups (Chao Yu, Fabian Frederick, Joe Perches)" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client: (40 commits) ceph: fix divide-by-zero in __validate_layout() rbd: rbd workqueues need a resque worker libceph: ceph-msgr workqueue needs a resque worker ceph: fix bool assignments libceph: separate multiple ops with commas in debugfs output libceph: sync osd op definitions in rados.h libceph: remove redundant declaration ceph: additional debugfs output ceph: export ceph_session_state_name function ceph: include the initial ACL in create/mkdir/mknod MDS requests ceph: use pagelist to present MDS request data libceph: reference counting pagelist ceph: fix llistxattr on symlink ceph: send client metadata to MDS ceph: remove redundant code for max file size verification ceph: remove redundant io_iter_advance() ceph: move ceph_find_inode() outside the s_mutex ceph: request xattrs if xattr_version is zero rbd: set the remaining discard properties to enable support rbd: use helpers to handle discard for layered images correctly ...
