commit 01b8b5713691316b09588b9c28117527b3c0d0c6 Author: Alex Hornung <ahornung at gmail.com> Date: Tue Jun 19 14:07:26 2012 +0100 puffs - don't lock dvp on nresolve * locking dvp on nresolve causes a deadlock with the puffsop thread when the dvp is the root vnode. * If a lookup/nresolve occurs at the same time as a flush via the puffsop, then puffsop will not be able to acquire a lock on the root vnode as the lookup routine already holds it. Similarly the lookup routine never gets woken up waiting for the message to arrive, since puffsop is stuck and can't reply.
