 Modified Files:
        src/sys/kern: vfs_vnode.c
 
 Log Message:
 Change vrelel() to mark the vnode as changing after it has aquired
 the vnode lock but before it calls VOP_INACTIVE().
 
 Should fix the race between layer_node_find() trying to vget(, LK_NOWAIT)
 a locked vnode when vrelel() marked it as changing and wants its lock.
