[GIT PULL] Block fixes for 4.11-rc2

From: Jens Axboe

Hi Linus,

Sending this a bit sooner than I otherwise would have, as a fix in the
merge window had some unfortunate issues and side effects for some

This pull request contains:

- Fixes from Jan for the bdi registration/unregistration. These have
been tested by the various parties reporting issues, and should be
solid at this point.

- Also from Jan, fix for axonram gendisk registration.

- A stable fix for zram from Johannes.

- A small series from Ming, fixing up some long standing issues with
blk-mq hardware queue kobject initialization and registration.

- A fix for sed opal from Jon, fixing a nonsensical range check and some
set-but-not-used variables.

- A fix from Neil for a long standing deadlock issue for stacking device
drivers. With this in place, dm/md don't have to work around the issue
anymore, and can be properly fixed up.

Please pull!
