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)
-> 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.
