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. > Hope I can have your ACK soon. 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 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.
