Jeff Roberson 698b1a6643 - Complete part of the unfinished bufobj work by consistently using ... BO_LOCK/UNLOCK/MTX when manipulating the bufobj. - Create a new lock in the bufobj to lock bufobj fields independently. This leaves the vnode interlock as an 'identity' lock while the bufobj is an io lock. The bufobj lock is ordered before the vnode interlock and also before the mnt ilock. - Exploit this new lock order to simplify softdep_check_suspend(). - A few sync related functions are marked with a new XXX to note that we may not properly interlock against a non-zero bv_cnt when attempting to sync all vnodes on a mountlist. I do not believe this race is important. If I'm wrong this will make these locations easier to find. Reviewed by: kib (earlier diff) Tested by: kris, pho (earlier diff)		2008-03-22 09:15:16 +00:00
