-Subject: [PATCH] Librados: Fix deadlock in watch_flush
-
-In previous code, in the watch_flush, it is waiting on conditon
-with holding the "lock". The condition will only be signal by
-finisher thread, but sadly, in some cases,when finisher queue
-is not empty, some context need to take the "lock", thus deadlock.
-
-To avoid concurrent call to shutdown cause race condition, add
-a shutdown_lock to ensure only one concurrent in shutdown function.
