Sorry about the delay.

There's a problem here.  For the blk layer dma padding itself, it's okay
but the problem is that it blocks the pending draining patch without
supplying usable alternative at the moment.  I agree that the long term
solution should be in the block layer && I understand that it causes
problem for SAS controllers but for the moment if we don't include the
existing draining patch, far more ATAPI devices are affected.  So, it's
catch-22 situation.

I think the best solution is to update block layer draining such that it
can be included together before the merge window closes.  I'll dig into it.

Thanks.
