[PATCH] radix_tag_get(): differentiate between no present node and tag unset cases
Simple patch to radix_tree_tag_get() to return different values for non present node and tag unset. The function is not used by any in-kernel callers (yet), but this information is definitely useful. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
