From 85bfb4da8cad483a4e550ec89060d05a4daf895b Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 22 Oct 2007 20:45:11 -0700 Subject: [PATCH] md: fix an unsigned compare to allow creation of bitmaps with v1.0 metadata As page->index is unsigned, this all becomes an unsigned comparison, which almost always returns an error.
