Merge tag 'io_uring-5.5-20191226' of git://git.kernel.dk/linux-block
Pull io_uring fixes from Jens Axboe:
- Removal of now unused busy wqe list (Hillf)
- Add cond_resched() to io-wq work processing (Hillf)
- And then the series that I hinted at from last week, which removes
the sqe from the io_kiocb and keeps all sqe handling on the prep
side. This guarantees that an opcode can't do the wrong thing and
read the sqe more than once. This is unchanged from last week, no
issues have been observed with this in testing. Hence I really think
we should fold this into 5.5.
* tag 'io_uring-5.5-20191226' of git://git.kernel.dk/linux-block:

io_uring: pass in 'sqe' to the prep handlers
io_uring: standardize the prep methods
io_uring: read 'count' for IORING_OP_TIMEOUT in prep handler
io_uring: move all prep state for IORING_OP_{SEND,RECV}_MGS to prep handler
io_uring: move all prep state for IORING_OP_CONNECT to prep handler
io_uring: add and use struct io_rw for read/writes

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.
