When the kernel detects it is oops or otherwise force killing a task while it exits the code poorly attempts to permanently stop the task from scheduling. I say poorly because it is possible for a task in TASK_UINTERRUPTIBLE to be woken up. As it makes no sense for the task to continue call do_task_dead instead which actually does the work and permanently removes the task from the scheduler. Guaranteeing the task will never be woken up again. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>
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.
