Description

[3/18/15, 11:01:00 AM] Andreas Dilger: The other thought I had was to replace the global dq_state_lock and dq_list_lock with per-sb spinlocks and a per-sb hash table, and use a separate lock for the dq_list_lock for the quota format calls
[3/18/15, 11:02:07 AM] Andreas Dilger: that would at least avoid lock contention between MDTs
