commit e6e2843230799230fc5deb8279728a7218b0d63c upstream. If the cluster becomes unavailable, ceph_osdc_notify() may hang even with osd_request_timeout option set because linger_notify_finish_wait() waits for MWatchNotify NOTIFY_COMPLETE message with no associated OSD request in flight -- it's completely asynchronous. Introduce an additional timeout, derived from the specified notify timeout. While at it, switch both waits to killable which is more correct.
