[PATCH vfs-2.6 6/6] vfs: add LOOKUP_RENAME_TARGET intent
This adds LOOKUP_RENAME_TARGET intent for lookup of rename destination. LOOKUP_RENAME_TARGET is going to be used like LOOKUP_CREATE. But since the destination of rename() can be existing directory entry, so it has a difference. Although that difference doesn't matter in my usage, this tells it to user of this intent.
