Subject: [PATCH] network: Don't fail on non-process PIDs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If the PID we have point to a kernel thread, /proc/PID/exe will not
exist and resolving the symlink will therefore fail.
In such cases, just go ahead with an empty path which will result in the
right behavior.
