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.

ndo_stop() is RTNL-protected by net core, and the worker function takes RTNL as well. Therefore we will deadlock when trying to execute a pending work synchronously. To fix this execute any pending work asynchronously. This will do no harm because netif_running() is false in ndo_stop(), and therefore the work function is effectively a no-op. However we have to ensure that no task is running or pending after rtl_remove_one(), therefore add a call to cancel_work_sync().
