In ext4_mb_normalize_request, the size of the allocation request is
limited to no more than EXT4_BLOCKS_PER_GROUP. Ritesh mentions that this
does not take into account the case of flex_bg groups. So we should add
support for flex_bg to make the physical blocks of large files contiguous.
My only concern here was that what if we are at the flex group end boundary and
decide to take the size as of flex group size. How are we detecting that case.
But, I haven't yet looked at this patch of yours (as I am on travel for next few days),
but if this requires further discussion, we can work on this seperately and let
the other two patches go in as those are part of the bug fixes which you
identified (just my thoughts).

All right, work on this separately.
Have a nice trip!
