linux-toradex.git/fs/ceph/debugfs.c, branch v3.3.5 Linux kernel for Apalis and Colibri modules ceph: explicitly reference rename old_dentry parent dir in request 2011-07-26T18:31:14+00:00 Sage Weil sage@newdream.net 2011-07-26T18:31:14+00:00 41b02e1f9bb87b07d792b64aaeb7af3d00d69cd2 We carry a pin on the parent directory for the rename source and dest dentries. For the source it's r_locked_dir; we need to explicitly reference the old_dentry parent as well, since the dentry's d_parent may change between when the request was created and pinned and when it is freed.

ceph: factor out libceph from Ceph file system 2010-10-20T22:37:28+00:00 Yehuda Sadeh yehuda@hq.newdream.net 2010-04-06T22:14:15+00:00 3d14c5d2b6e15c21d8e5467dc62d33127c23a644 This factors out protocol and low-level storage parts of ceph into a separate libceph module living in net/ceph and include/linux/ceph. This is mostly a matter of moving files around. However, a few key pieces of the interface change as well: - ceph_client becomes ceph_fs_client and ceph_client, where the latter captures the mon and osd clients, and the fs_client gets the mds client and file system specific pieces. - Mount option parsing and debugfs setup is correspondingly broken into two pieces. - The mon client gets a generic handler callback for otherwise unknown messages (mds map, in this case). - The basic supported/required feature bits can be expanded (and are by ceph_fs_client). No functional change, aside from some subtle error handling cases that got cleaned up in the refactoring process. Signed-off-by: Sage Weil <sage@newdream.net>
