Xin LI b4bb49887b Reduce lock contention on the z_teardown_lock under heavily cached ... read workload by splitting the single teardown rrw lock into RRM_NUM_LOCKS (17) of them. Read acquisitions are randomly distributed among these locks based on curthread pointer. Write acquisitions are going to all the locks, which for the usage of this type of lock should be rare. Illumos issue: 5008 lock contention (rrw_exit) while running a read only load MFC after: 2 weeks		2014-07-19 00:26:03 +00:00
