OK I'm disegarding the redirect for non-parmap for now but we'd have to determine if we want to append or add one per PID...

When you run scripts/coccicheck we take the absolute directory of it and then go down one level of directory, so in this case it would be the base directory of the Linux kernel. $$ is the PID of the bash script.
