Tried to do this:

reinoud@router-dev:~/Downloads/kernel_current$ git remote add xfsdev
git://git.kernel.org/git/dgc/linux-xfs.git
reinoud@router-dev:~/Downloads/kernel_current$ git remote update
Fetching origin
Fetching xfsdev
fatal: remote error: access denied or repository not exported:
/git/dgc/linux-xfs.git
error: Could not fetch xfsdev

I don't think I have access to git.kernel.org in terms of pushing. :)
Or am I doing something else wrong.
Forgive the trivial question.

Btw, I started in the most current linus git tree.... or should I git
4.6.y and then do your suggestions?

Thanks,

Reinoud.
