Modified Files:
src/sys/kern: vfs_lookup.c
Log Message:
- lookup_once: 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.
- lookup_parsepath: don't alter vnode states. let the caller do it instead.
- add comments and assertions.
