This is done in preparation for handling more than one ctx, but it also cleans up the code a bit since io_sq_thread() was a bit too unwieldy to get a get overview on. __io_sq_thread() is now the main handler, and it returns an enum sq_ret that tells io_sq_thread() what it ended up doing. The parent then makes a decision on idle, spinning, or work handling based on that. Signed-off-by: Jens Axboe <axboe@kernel.dk>
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.
