Hi Greg,
Please also pick up this commit: 89f5fa47476eda56402e29fff3c5097f5c2a1e19 ("dm: call blk_queue_split() to impose device limits on bios")
Thanks, Mike
But.. looking closer, since you're backporting to 4.4, to even have DM be able to use bio_split() you'll need these 3 commits too:
18a25da84354c6bb655320de6072c00eda6eb602 ("dm: ensure bio submission follows a depth-first tree walk") 8dd601fa8317243be887458c49f6c29c2f3d719f ("dm: correctly handle chained bios in dec_pending()") f21c601a2bb319ec19eb4562eadc7797d90fd90e ("dm: use bio_split() when splitting out the already processed bio")
