Since VFS_FHTOVP() currently always gets an exclusively locked vnode and is usually called at the beginning of each RPC, the RPCs for a given vnode will still be serialized. As such, passing a lock type argument to VFS_FHTOVP() would be preferable to doing the vn_lock() with LK_DOWNGRADE after the VFS_FHTOVP() call. END
