Merge tag 'io_uring-5.5-20191220' of git://git.kernel.dk/linux-block
Pull io_uring fixes from Jens Axboe:
"Here's a set of fixes that should go into 5.5-rc3 for io_uring.
This is bigger than I'd like it to be, mainly because we're fixing the
case where an application reuses sqe data right after issue. This
really must work, or it's confusing. With 5.5 we're flagging us as
submit stable for the actual data, this must also be the case for
SQEs.
Honestly, I'd really like to add another series on top of this, since
it cleans it up considerable and prevents any SQE reuse by design. I
posted that here:
https://lore.kernel.org/io-uring/20191220174742.7449-1-axboe@kernel.dk/T/#u
and may still send it your way early next week once it's been looked
at and had some more soak time (does pass all regression tests). With
that series, we've unified the prep+issue handling, and only the prep
phase even has access to the SQE.
Anyway, outside of that, fixes in here for a few other issues that
have been hit in testing or production"

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.
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.
