Merge tag 'for-linus-20180425' of git://git.kernel.dk/linux-block
Pull block updates from Jens Axboe:
"I ended up sitting on this about a week longer than I wanted to, since
we were hashing out details with a timeout change. I've now killed
that patch, so we can flush the existing queue in due time.
This contains:
- Fix for an old regression, where entering the queue can be
disturbed by a signal to the process. This can cause spurious EIO.
Fix from Alan Jenkins.
- cdrom information leak fix from Dan.
- Trivial helper for testing queue FUA from Dave Chinner, part of his
O_DIRECT FUA series.
- Series of swim fixes from Finn that actually makes it work again.
- Loop O_DIRECT corruption fix, which caused data corruption in
production for us. From me.
- BFQ crash fix from me.
- bcache maintainer update. Michael no longer has the time to do it,
Coly has stepped up to serve as the new maintainer.
- blkcg locking fixes from Jiang Biao.
- Revert of a change from this merge window from Ming, that causes an
issue on some hardware.
- Minor clarification doc addition from Linus Walleij"

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
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.
