Some of the tun_debug() statements only inform us about entering a function which can be easily achieved with ftrace or kprobe. As tun_debug() is no-op unless TUN_DEBUG is set which requires editing the source and recompiling, setting up ftrace or kprobe is easier. Drop these debug statements. Also drop the tun_debug() statement informing about SIOCSIFHWADDR ioctl. We can monitor these through rtnetlink and it makes little sense to log address changes through ioctl but not changes through rtnetlink. Moreover, this tun_debug() is called even if the actual address change fails which makes it even less useful. Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Signed-off-by: David S.

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.
