[PATCH] buglet in radix_tree_tag_set
The comment states: 'Setting a tag on a not-present item is a BUG.' Hence if 'index' is larger than the maxindex; the item _cannot_ be presen; it should also be a BUG. Also, this allows the following statement (assume a fresh tree): radix_tree_tag_set(root, 16, 1); to fail silently, but when preceded by: radix_tree_insert(root, 32, item); it would BUG, because the height has been extended by the insert. In neither case was 16 present. Signed-off-by:Peter Zijlstra <a.p.zijlstra@chello.nl> Acked-by:
