Continuing with the theme of locking older storage drivers, I have patches to add locking to adv(4) and mark it MPSAFE. The patches are from HEAD but should apply to 8 or 9. If you test it on 8 or 9 please enable INVARIANTS for at least the initial testing. Thanks. http://www.FreeBSD.org/~jhb/patches/adv_locking.patch -- John Baldwin
