Description
As for now, when there are multiple concurrent threads trying to access the same file, there might be a chance that they all send "getattr", "lookup", "ceph_sync_read" requests to MDSes, which could severly increase the load of MDSes.
So, we implemented a way that aggregate those duplicate requests and sending only one request on behalf of all others.
