The big change is the removal of the lock hierarchy. James - could you please apply these incoming patches to the scsi-locking-2.5 tree, comment, and/or push to Linus (or scsi-misc)? If the opinion is that this needs more runtime, other changes, or more performance comparisons, I can do so. The patches do seem to increase the likelyhood of hitting a race in the aic driver (the patch Zwane posted to have aic use del_timer_sync, and is currently in the akpm mm patch). I do not think the extra blk queue init/frees are bad, especially with Jens working on dynamic req allocation. Thanks. -- Patrick Mansfield
