ext4: allocate stripe-multiple IOs on stripe boundaries
For some reason, today mballoc only allocates IOs which are exactly
stripe-sized on a stripe boundary. If you have a multiple (say, a
128k IO on a 64k stripe) you may end up unaligned.
It seems to me that a simple change to align stripe-multiple IOs
on stripe boundaries would be a very good idea, unless this breaks
some other mballoc heuristic for some reason...
