MFC r286763: 5497 lock contention on arcs_mtx
Reviewed by: George Wilson <george.wilson@delphix.com> Reviewed by: Matthew Ahrens <mahrens@delphix.com> Reviewed by: Richard Elling <richard.elling@richardelling.com> Approved by: Dan McDonald <danmcd@omniti.com> Author: Prakash Surya <prakash.surya@delphix.com>

This patch attempts to reduce lock contention on the current arc_state_t mutexes. These mutexes are used liberally to protect the number of LRU lists within the ARC (e.g. ARC_mru, ARC_mfu, etc). The granularity at which these locks are acquired has been shown to greatly affect the performance of highly concurrent, cached workloads.
