Many operations define custom work.func before getting into an io-wq. There are several points against: - it calls io_wq_assign_next() from outside io-wq, that may be confusing - sync context would go unnecessary through io_req_cancelled() - prototypes are quite different, so work!=old_work looks strange - makes async/sync responsibilities fuzzy - adds extra overhead Don't call generic path and io-wq handlers from each other, but use helpers instead Signed-off-by: Pavel Begunkov <asml.silence@gmail.com> 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.
