* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client: (22 commits) ceph: do not carry i_lock for readdir from dcache fs/ceph/xattr.c: Use kmemdup rbd: passing wrong variable to bvec_kunmap_irq() rbd: null vs ERR_PTR ceph: fix num_pages_free accounting in pagelist ceph: add CEPH_MDS_OP_SETDIRLAYOUT and associated ioctl. ceph: don't crash when passed bad mount options ceph: fix debugfs warnings block: rbd: removing unnecessary test block: rbd: fixed may leaks ceph: switch from BKL to lock_flocks() ceph: preallocate flock state without locks held ceph: add pagelist_reserve, pagelist_truncate, pagelist_set_cursor ceph: use mapping->nrpages to determine if mapping is empty ceph: only invalidate on check_caps if we actually have pages ceph: do not hide .snap in root directory rbd: introduce rados block device (rbd), based on libceph ceph: factor out libceph from Ceph file system ceph-rbd: osdc support for osd call and rollback operations ceph: messenger and osdc changes for rbd ...
