From 538452700d95480c16e7aa6b10ff77cd937d33f4 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Fri, 9 Jan 2009 08:31:05 +1100 Subject: [PATCH] md: fix bitmap-on-external-file bug. commit a2ed9615e3222645007fc19991aedf30eed3ecfd fixed a bug with 'internal' bitmaps, but in the process broke 'in a file' bitmaps. So they are broken in 2.6.28 This fixes it, and needs to go in 2.6.28-stable.
