2016-08-24rbd: support for exclusive-lock featureIlya Dryomov
Add basic support for RBD_FEATURE_EXCLUSIVE_LOCK feature. Maintenance operations (resize, snapshot create, etc) are offloaded to librbd via returning -EOPNOTSUPP - librbd should request the lock and execute the operation.

2016-05-25libceph, rbd: ceph_osd_linger_request, watch/notify v2Ilya Dryomov
This adds support and switches rbd to a new, more reliable version of watch/notify protocol. As with the OSD client update, this is mostly about getting the right structures linked into the right places so that reconnects are properly sent when needed. watch/notify v2 also requires sending regular pings to the OSDs - send_linger_ping(). A major change from the old watch/notify implementation is the introduction of ceph_osd_linger_request - linger requests no longer piggy back on ceph_osd_request. ceph_osd_event has been merged into ceph_osd_linger_request. All the details are now hidden within libceph, the interface consists of a simple pair of watch/unwatch functions and ceph_osdc_notify_ack(). ceph_osdc_watch() does return ceph_osd_linger_request, but only to keep the lifetime management simple. ceph_osdc_notify_ack() accepts an optional data payload, which is relayed back to the notifier. Portions of this patch are loosely based on work by Douglas Fuller <dfuller@redhat.com> and Mike Christie <michaelc@cs.wisc.edu>. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

2010-10-20ceph: factor out libceph from Ceph file systemYehuda Sadeh
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>
