Guillaume Nault says: ==================== selftests: pmtu.sh: Fix cleanup of processes launched in subshell. Depending on the options used, pmtu.sh may launch tcpdump and nettest processes in the background. However it fails to clean them up after the tests complete. Patch 1 allows the cleanup() function to read the list of PIDs launched by the tests. Patch 2 fixes the way the nettest PIDs are retrieved. ==================== Link: https://lore.kernel.org/r/cover.1646776561.git.gnault@redhat.com Signed-off-by: Jakub Kicinski <kuba@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.
