Modified Files:
        src/sys/kern: vfs_lookup.c

Log Message:
redo vfs_lookup.c rev.1.126.
when crossing a mount point, don't keep the parent vnode locked.
ie. don't lock a vnode while holding another vnode which belongs to a
different filesystem.  otherwise we propagate slowness (or deadness) of a
filesystem to another via vnode lock chain.
