io_uring offloads task_work for cancelation purposes when the task is exiting. This is conceptually fine, but we should be nicer and actually wait for that work to complete before returning. Add an argument to io_fallback_tw() telling it to flush the deferred work when it's all queued up, and have it flush a ctx behind whenever the ctx changes. 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.
