* Some worker fields are modified only by the worker itself while holding pool->lock thus making them safe to read from self, IRQ context if the CPU is running the worker or while holding pool->lock. Add 'K' locking rule for them. * worker->sleeping is currently marked "None" which isn't very descriptive. It's used only by the worker itself. Add 'S' locking rule for it. A future patch will depend on the 'K' rule to access worker->current_* from the scheduler ticks. 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.
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.
