2.2.16 md botch; please revert

The otherwise excellent (!) 2.2.16 patch includes a change to
drivers/block/md.c that breaks my raid0 setup. The change sets the md
device's block size to the RAID chunk size. Unfortunately, that causes
a total failure when the chunk size is larger than PAGE_SIZE, which it
is in my case (16K chunks, 4K page size).

Here is a patch that reverts the 2.2.16 change and makes it work for
me again. I'm curious to know what the change was supposed to do....

Index: drivers/block/md.c
*************** static int do_md_run (int minor, int rep
*** 447,452 ****
factor = min = 1 << FACTOR_SHIFT(FACTOR((md_dev+minor)));

- md_blocksizes[minor] <<= FACTOR_SHIFT(FACTOR((md_dev+minor)));
-
for (i=0; i<md_dev[minor].nb_dev; i++)
if (md_dev[minor].devices[i].size<min)
