Cover letter [patch 0/3] raid5: relieve lock contention of get_active_stripe()
Neil,
This is to relieve lock contention of get_active_stripe(), which is the last place we have lock contention in stripe handling. For small size random write, we have no lock contention now. For big size write, lock contention is still there. Please check the third patch for detail.
Thanks,
Shaohua
