Michal Kubecek says: ==================== tun: debug messages cleanup While testing ethtool output for "strange" devices, I noticed confusing and obviously incorrect message level information for a tun device and sent a quick fix. The result of the upstream discussion was that tun driver would rather deserve a more complex cleanup of the way it handles debug messages. The main problem is that all debugging statements and setting of message level are controlled by TUN_DEBUG macro which is only defined if one edits the source and rebuilds the module, otherwise all DBG1() and tun_debug() statements do nothing. This series drops the TUN_DEBUG switch and replaces custom tun_debug() macro with standard netif_info() so that message level (mask) set and displayed using ethtool works as expected. Some debugging messages are dropped as they only notify about entering a function which can be done easily using ftrace or kprobe. Patch 1 is a trivial fix for compilation warning with W=1. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
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.
