2.6.28-stable review patch. If anyone has any objections, please let us know.
------------------
From: NeilBrown <neilb@suse.de>
commit 538452700d95480c16e7aa6b10ff77cd937d33f4 upstream.
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.
