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
