+ Previous caused a deadlock with layered FS: the vrele thread can
+ sleep on the vnode lock, while vget is sleeping on the
+ VI_INACTNOW flag (or the vget caller is looping on vget returning
+ failure because of the VI_INACTNOW flag). With layered FSes,
+ the upper and lower vnodes share the same lock, so the vget()
+ caller above can be already holding the vnode lock.
+ Fix by dropping VI_INACTNOW before sleeping on the vnode lock in
+ vrelel(), and check the ref count again once we have the lock.
+ If the vnode has more than one reference, don't VOP_INACTIVE it.
+ Fix PR kern/42318 and PR kern/42377
