Yes sure, this pull request contains:

- NVMe updates and fixes that missed the first pull request. This
  includes bug fixes, and support for autonomous power management.

- Fix from Christoph for missing clear of the request payload,
  causing a problem with (at least) the storvsc driver.

- Further fixes for the queue/bdi life time issues from Jan.

- The Kconfig mq scheduler update from me.

- Fixing a use-after-free in dm-rq, spotted by Bart, introduced
  in this merge window.

- Three fixes for nbd from Josef.

- Bug fix from Omar, fixing a bug in sas transport code that
  oopses when bsg ioctls were used. From Omar.

- Improvements to the queue restart and tag wait from from
  Omar.

- Set of fixes for the sed/opal code from Scott.

- Three trivial patches to cciss from Tobin

It's a puzzling issue. Let me know how it goes with the above merge, and
I can add some debug code to try and narrow this down.
