While testing tdc with parallel tests for mirred to block we caught an
intermittent bug. The blockid was being zeroed out when a net device
was deleted and, thus, giving us an incorrect blockid value whenever
we tried to dump the mirred action. Since we don't increment the block
refcount in the control path (and only use the ID), we don't need to
zero the blockid field whenever a net device is going down.

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.
