Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client
Pull Ceph updates from Sage Weil: "This has a mix of bug fixes and cleanups. Alex's patch fixes a rare race in RBD. Ilya's patches fix an ENOENT check when a second rbd image is mapped and a couple memory leaks. Zheng fixes several issues with fragmented directories and multiple MDSs. Josh fixes a spin/sleep issue, and Josh and Guangliang's patches fix setting and unsetting RBD images read-only. Naturally there are several other cleanups mixed in for good measure" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client: (23 commits) rbd: only set disk to read-only once rbd: move calls that may sleep out of spin lock range rbd: add ioctl for rbd ceph: use truncate_pagecache() instead of truncate_inode_pages() ceph: include time stamp in every MDS request rbd: fix ida/idr memory leak rbd: use reference counts for image requests rbd: fix osd_request memory leak in __rbd_dev_header_watch_sync() rbd: make sure we have latest osdmap on 'rbd map' libceph: add ceph_monc_wait_osdmap() libceph: mon_get_version request infrastructure libceph: recognize poolop requests in debugfs ceph: refactor readpage_nounlock() to make the logic clearer mds: check cap ID when handling cap export message ceph: remember subtree root dirfrag's auth MDS ceph: introduce ceph_fill_fragtree() ceph: handle cap import atomically ceph: pre-allocate ceph_cap struct for ceph_add_cap() ceph: update inode fields according to issued caps rbd: replace IS_ERR and PTR_ERR with PTR_ERR_OR_ZERO ...
