When we want to debug the workqueue stall, we can immediately make a panic to get the information we want. In some systems, it may be necessary to quickly reboot the system to escape from a workqueue lockup situation. In this case, we can control the number of stall detections to generate panic. workqueue.panic_on_stall sets the number times of the stall to trigger panic. 0 disables the panic on stall.

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 reStructuredText 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.
