Ilya Dryomov 2e5522ad5c libceph: wait for latest osdmap in ceph_monc_blacklist_add() ... commit bb229bbb3b upstream. Because map updates are distributed lazily, an OSD may not know about the new blacklist for quite some time after "osd blacklist add" command is completed. This makes it possible for a blacklisted but still alive client to overwrite a post-blacklist update, resulting in data corruption. Waiting for latest osdmap in ceph_monc_blacklist_add() and thus using the post-blacklist epoch for all post-blacklist requests ensures that all such requests "wait" for the blacklist to come into force on their respective OSDs.
