Al, list,

In order to accessing my md devices in 2.5.43, i needed the attached
patch to fs/block_dev.c. WARNING: it's probably very broken, because I
don't know what I'm doing. I essentially reverted most of the changes to
the do_open function, allowing the open() method of a device without an
attached gendisk to be called.

In the md scheme of things, the gendisk is created in the md_run stage,
which is only possible via ioctl after a successful open of the block
device.

However, something else is broken with the change to md.c, which detects
whether the disk is idle by checking the number of sectors read/written to
the disk.

I'm going to take a look at that now.

David
