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> |
