Merge tag 'for-5.11/io_uring-2020-12-14' of git://git.kernel.dk/linux-block
Pull io_uring updates from Jens Axboe:
"Fairly light set of changes this time around, and mostly some bits
that were pushed out to 5.11 instead of 5.10, fixes/cleanups, and a
few features. In particular:
- Cleanups around iovec import (David Laight, Pavel)
- Add timeout support for io_uring_enter(2), which enables us to
clean up liburing and avoid a timeout sqe submission in the
completion path.
The big win here is that it allows setups that split SQ and CQ
handling into separate threads to avoid locking, as the CQ side
will no longer submit when timeouts are needed when waiting for
events (Hao Xu)
- Add support for socket shutdown, and renameat/unlinkat.
- SQPOLL cleanups and improvements (Xiaoguang Wang)
- Allow SQPOLL setups for CAP_SYS_NICE, and enable regular
(non-fixed) files to be used.
- Cancelation improvements (Pavel)
- Fixed file reference improvements (Pavel)
- IOPOLL related race fixes (Pavel)
- Lots of other little fixes and cleanups (mostly Pavel)"

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.
