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

Log Message:
Modify how lookup walks up mount points. As suggested by Konrad
Schroder <perseant@hitl.washington.edu>, unlock the mounted on
vnode before we call VFS_ROOT so that we cover the case where the new
root vnode shares a lock with the mounted-on vnode. Note that we have
asserted vfs_busy on the new fs before unlocking, so no other process can
steal the mount out from under us.
