[dm-devel] [for-4.16 PATCH v5 0/4] block/dm: allow DM to defer blk_register_queue() until ready

[Mike Snitzer]

Hi Jens,

I'm submitting this v5 with more feeling now ;)

I've distilled the changes down to be quite minimal.  Hopefully this
will help you and others review.

I've also done a dry-run of applying 4.16 block changes and then
merging dm-4.16; no merge conflicts:

https://git.kernel.org/pub/scm/linux/kernel/git/snitzer/linux.git/log/?h=block-4.16_dm-4.16

And all tests very well for me.

Please consider for 4.16, thanks!

Mike
