Faster SCSI, new objcache to test

Gary Stanley (‘Ancient’ on #dragonflybsd) has posted a patch against the most recent DragonFly sources that adds SCSI domain validation. It ought to work on older releases, too.

The name isn’t exciting, but SCSI domain validation ensures your SCSI bus runs as fast as possible. If you have the hardware for it, try it out.

Also, if you’re in a testing mood, Matthew Dillon has posted a new version of kern_objcache.c, using spinlocks instead of tokens, coming from a longer conversation detailing locking models in DragonFly.
