This is going to be important for future block layer refactoring, and
using the standard primitives makes the code easier to audit.

Update block/biovecs.txt so that it includes a note on what kind of
effects arbitrarily sized bios would bring to the block layer.
Also fix a trivial typo, bio_iter_iovec.

Remove bio_fits_rdev() completely, because ->merge_bvec_fn() has now

Are you seeing it without any back traces?
Does the attached patch fix your issue?
(This is already included in the branch block-mpage-bvecs-for-next.)

I have been already satisfied with Neil's patch,
but your patch looks indeed a lot cleaner, I like it.
I just compiled and tested it sh
to_create_worker() as Tejun suggested.
Test is running with this patch, which seems to be working for now.
But I'm going to observe the test result carefully for a few more days.

Dongsu
