Not all mutexes are dynamically allocated. Also, you have to really be careful here. There may not be much of a point in spending all this time re-aligning the actual lock knob in the structure, which is accessed atomically with the bus locked all the time. There are a lot of structures which could probably be re-organized for cache gain purposes but at this point we have so many structures changing so quickly that this sort of change becomes difficult to do properly. -- Bosko Milekic * [EMAIL PROTECTED] * [EMAIL PROTECTED] TECHNOkRATIS Consulting Services * http://www.technokratis.com/ _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
