Pull block fixes from Jens Axboe:
"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
folks.
This 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"

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
