Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client: ceph: ensure prealloc_blob is in place when removing xattr rbd: initialize snap_rwsem in rbd_add() ceph: enable/disable dentry complete flags via mount option vfs: export symbol d_find_any_alias() ceph: always initialize the dentry in open_root_dentry() libceph: remove useless return value for osd_client __send_request() ceph: avoid iput() while holding spinlock in ceph_dir_fsync ceph: avoid useless dget/dput in encode_fh ceph: dereference pointer after checking for NULL crush: fix force for non-root TAKE ceph: remove unnecessary d_fsdata conditional checks ceph: Use kmemdup rather than duplicating its implementation Fix up conflicts in fs/ceph/super.c (d_alloc_root() failure handling vs always initialize the dentry in open_root_dentry)
