Because in some cases its necessary for a process to acquire mutexes while its on the sleep queue.

It seems to me that whatever gets placed on the run queues should also be what goes on the mutex queues. > > -- > +------------------------------------+ ______ _ __ > | __--_|\ Julian Elischer | \ U \/ / hard at work in > | / \ julian@elischer.org +------>x USA \ a very strange > | ( OZ ) \___ ___ | country ! > +- X_.---._/ presently in San Francisco \_/ \\ > v > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-current" in the body of the message To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
