The following reply was made to PR kern/172166; it has been noted by GNATS. From: Alexander Motin <mav@FreeBSD.org> To: bug-followup@FreeBSD.org, eugen@eg.sd.rdtc.ru Cc: Andriy Gapon <avg@FreeBSD.org> Subject: Re: kern/172166: Deadlock in the networking code, possible due to a bug in the SCHED_ULE Date: Tue, 02 Oct 2012 09:58:00 +0300 About rw_lock priority propagation locking(9) tells: The rw_lock locks have priority propagation like mutexes, but priority can be propagated only to an exclusive holder. This limitation comes from the fact that shared owners are anonymous. What's about idle stealing threshold, it was fixed in HEAD at r239194, but wasn't merged yet. It should be trivial to merge it. -- Alexander Motin
