Work functions can use set_worker_desc() to improve the visibility of what the worker task is doing. Currently, the desc field is unset at the beginning of each execution and there is a separate field to track the field is set during the current execution. Instead of leaving empty till desc is set, worker->desc can be used to remember the last workqueue the worker worked on by default and users that use set_worker_desc() can override it to something more informative as necessary. This simplifies desc handling and helps tracking the last workqueue that the worker exected on to improve visibility. Signed-off-by: Tejun Heo <tj@kernel.org>
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
