OK I'll blacklist all branches containing the "chrome" string.
It's "grep -E" patterns. Here are some examples:
wfg /c/lkp-tests% grep -hr blacklist repo
blacklist_branch: master|revert-
blacklist_branch: .*
blacklist_branch: .*
blacklist_branch: .*
blacklist_branch: for-epmt
blacklist_branch: master
blacklist_branch: pending-rebases
blacklist_branch: for_3.16/wip/net-qmss5
blacklist_branch: auto-next
blacklist_branch: .*
blacklist_branch: .*
blacklist_branch: cpufreq-tixy
blacklist_branch: .*\<stable\>
blacklist_branch: akpm|akpm-base|stable
blacklist_branch: dev
blacklist_branch: .*
blacklist_branch: auto-.*|tmp-.*|base-.*|test.*|.*-for-linus
blacklist_branch: nx-emu
blacklist_branch: .*
blacklist_branch: master
blacklist_branch: master
blacklist_branch: unionmount
blacklist_branch: check
blacklist_branch: devel/.*
blacklist_branch: rerere-cache|maintainer-tools
blacklist_branch: .*
blacklist_branch: auto-next
blacklist_branch: .*
blacklist_branch: .*
blacklist_branch: openrisc-4.12-smp
blacklist_branch: master|revert-
blacklist_branch: master|revert-
blacklist_branch: master|revert-
blacklist_branch: master|revert-
blacklist_branch: master|revert-
blacklist_branch: master|revert-
Thanks,
