You will be happy to know that yes, it does make a difference.

Applied to -mm4, RAID-1 now comes up with all arrays in sync and everything looking good. Tried it twice, and both times raid-1 came up perfectly with

md0 : active raid1 sdc2[1] sda2[0]
24410688 blocks [2/2] [UU]
bitmap: 0/187 pages [0KB], 64KB chunk

for each md.

Cool.... so who is giving us that EIO. I'm guessing
end_that_request_first or .._last, but where is it getting to there
from?

What is you remove that last patch (so it still tries barrier writes)
but add this patch (so WARN_ON gives us a trace when it happens).

Bear in mind that this does not include Ingo's fix for the md stuff:
