https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=262587 --- Comment #16 from Mark Johnston <markj@FreeBSD.org> --- (In reply to Alexander Motin from comment #15) The lock can change if umtxq_requeue() moves the queue to a different hash chain. With PDROP, the subsequent umtxq_lock(&uq->uq_key) will lock the new chain. Right now we are re-locking the old one. -- You are receiving this mail because: You are the assignee for the bug.
