Thanks Gui. Can't think of a reason why "curr" should be a separate
function argument. I could only find blk_get_request() to be calling
io_get_io_group() without any bio passed. I think even in that case
determining the group from task should not hurt, I guess.

I will apply the patch.  Couple of comments inline.

Can we now change above to single statement

		io_get_io_group(q, bio, 1);
if bio is present, we will determine the group from that otherwise from
curret task context.

Same here. Get rid of "if" condition.

"if" not required now.
