I've merged your latest branch with my dm-4.3 branch, I had one conflict
in the merge due to the dm_merge_bvec() change from 4.2-rc6 (no
surprise).  I've published the result here:
http://git.kernel.org/cgit/linux/kernel/git/snitzer/linux.git/log/?h=block-late-bio-splitting

It passes the device-mapper-test-suite's 'thin-provisioning' tests.

Shouldn't we also be using MAX_BIO_SECTORS in blkdev_issue_write_same
(instead of UINT_MAX >> 9)?

Aside from that, I'm in favor of seeing this late bio splitting patchset
finally land upstream (hopefully in time for the 4.3 merge, Jens?):

Acked-by: Mike Snitzer <snitzer@xxxxxxxxxx>

p.s. I'll be working with Joe Thornber on optimizing DM (particularly
dm-thinp and dm-cache) once this patchset is included upstream.  You'll
see I've already added a couple WIP dm-thinp patches ontop.
