marcel 2009-12-14 01:26:01 UTC FreeBSD src repository Modified files: lib/libthr/thread thr_umtx.c Log: SVN rev 200498 on 2009-12-14 01:26:01Z by marcel Work-around a race condition on ia64 while unlocking a contested lock. The race condition is believed to be in UMTX_OP_MUTEX_WAKE. On ia64, we simply go to the kernel to unlock. The big question is why this is only a race condition on ia64...
