[PATCH] Futex lock division
From: "Hu, Boris" <boris.hu@intel.com>
Andrew reminded me of this.
Simple change to split the futex lock into a per-hashchain lock.
Don't bother cacheline aligning: Jamie points out that increasing
FUTEX_HASHBITS would have more payoff.
Ulrich Drepper reports 6% improvement in on a 4way futex-thrashing
benchmark.
