Description
Currently, it is possible for the filestore finisher threads to block trying to acquire a pg lock in order to complete an op. This might cause that op to block until a filestore sync happens.
commit callback (filestore finisher)(pg lock)> object recovery(filestore throttle)> filestore sync
The filestore throttles should be modified so that the various OSD queues can throttle before dispatching an op based on a max op write size.
