Hey Jens, I _think_ we've resolved the issues Bart raised for request-based DM's support for blk-mq devices (anything remaining seems specific to iSER's blk-mq support which is in development). Though Keith did have that one additional patch for that block scatter gather attribute that we still need to review closer. Anyway, I think what we have is a solid start and see no reason to hold these changes back further. So I've rebased the 'dm-for-3.20' branch of linux-dm.git ontop of 3.19-rc6 and reordered the required block changes to be at the front of the series, see: https://git.kernel.org/cgit/linux/kernel/git/device-mapper/linux-dm.git/log/?h=dm-for-3.20 (these changes have been in Linux next for a month, via linux-dm.git 'for-next') With your OK, I'd be happy to carry the required block changes and ultimately request Linus pull them for 3.20 (I can backfill your Acks if you approve). BUT I also have no problem with you picking up the block changes to submit via your block tree (I'd just have to rebase ontop of your 3.20 branch once you pull them in). Let me know what you think, thanks. Mike -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
