https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=262587 --- Comment #17 from Dmitry Chagin <dchagin@FreeBSD.org> --- Hi, Alexander! Yes, umtxq_requeue() relies on previous behaviour of umtxq_sleep(), where the lock dropped and reacquired, as umtxq_requeue() replaces the lock. A year ago, we discussed this block with kib@ and decided that it was safe to drop/acuire it. -- You are receiving this mail because: You are the assignee for the bug.
