ceph: factor out libceph from Ceph file system

2010-10-20T22:37:28+00:00

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

ceph: generalize mon requests, add pool op support

2010-08-10T21:41:25+00:00

Generalize the current statfs synchronous requests, and support pool_ops. Signed-off-by: Yehuda Sadeh Signed-off-by: Sage Weil

ceph: use complete_all and wake_up_all

2010-07-27T20:11:17+00:00

This fixes an issue triggered by running concurrent syncs. One of the syncs would go through while the other would just hang indefinitely. In any case, we never actually want to wake a single waiter, so the *_all functions should be used. Signed-off-by: Yehuda Sadeh Signed-off-by: Sage Weil

ceph: some endianity fixes

2010-06-13T17:34:36+00:00

Fix some problems that came up with sparse. Signed-off-by: Yehuda Sadeh Signed-off-by: Sage Weil

ceph: fix memory leak in statfs

ceph: do not resend mon requests on auth ticket renewal

2010-05-29T16:12:38+00:00

We only want to send pending mon requests when we successfully authenticate. If we are already authenticated, like when we renew our ticket, there is no need to resend pending requests. Signed-off-by: Sage Weil

ceph: reuse mon subscribe message instead of allocated anew

2010-05-21T23:26:11+00:00

Use the same message, allocated during startup. No need to reallocate a new one each time around (and potentially ENOMEM). Signed-off-by: Sage Weil

ceph: avoid resending queued message to monitor

2010-05-21T22:01:22+00:00

The auth_reply handler will (re)send any pending requests. For the initial mon authenticate phase, that's correct, but when a auth ticket renewal races with an in-flight request, we may resend a request message that is already in flight. Avoid this by revoking the message before sending it. We should also avoid resending requests at all during ticket renewal; that will come soon. Signed-off-by: Sage Weil

ceph: Storage class should be before const qualifier

2010-05-21T22:01:21+00:00

The C99 specification states in section 6.11.5: The placement of a storage-class specifier other than at the beginning of the declaration specifiers in a declaration is an obsolescent feature. Signed-off-by: Tobias Klauser Signed-off-by: Sage Weil

ceph: all allocation functions should get gfp_mask

2010-05-17T22:25:42+00:00

This is essential, as for the rados block device we'll need to run in different contexts that would need flags that are other than GFP_NOFS. Signed-off-by: Yehuda Sadeh Signed-off-by: Sage Weil
