hi,
looks like it's not pushed out?

[jolsa@krava perf]$ git remote -v | grep andi
andi    git://git.kernel.org/pub/scm/linux/kernel/git/ak/linux-misc.git (fetch)
andi    git://git.kernel.org/pub/scm/linux/kernel/git/ak/linux-misc.git (push)
[jolsa@krava perf]$ git remote update andi
Fetching andi
[jolsa@krava perf]$ git branch -r | grep metric-group
[jolsa@krava perf]$ git branch -r | grep intel-json-metrics-2
[jolsa@krava perf]$ 


thanks,
jirka
