So, I agree with Mark here. We should retry and fail bio-by-bio. The
end effect wouldn't be much worse than block-by-block while taking much

And perhaps flip the bio list backwards as well 8) ?
Reversing I/O lists might be the thing to do, but it gets really
complex at the low level. Drives don't have commands to read
sectors in reverse order. So to reverse the I/O, each single
command would have to be broken out into possibly thousands
of individual reads..
Not something I'd want to implement, but that's why we have Tejun! ;)
