Would like to see before vs after with: http://git.kernel.dk/cgit/linux-block/log/?h=for-4.21/block vs https://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git/log/?h=block-dm-4.21-inflight (block-dm-4.21-inflight is based on latest for-4.21/block -- and it contains DM changes in front of the block changes from this thread; I'd prefer Jens take the changes like this rather than leave DM in a bit of a mess for me/us to have to cleanup later)
