Subject: Run generator_kernel on master and keep the version state
X-Git-Url: http://git.liburcu.org/?a=commitdiff_plain;h=0b51cf960f9661e8c6e2fd2ef13903691d24d5e1;p=lttng-ci.git

Run generator_kernel on master and keep the version state

Since the rc are deleted based on the previous version file it's imperative to
keep it from time to time to ensure deletion of unwanted rc jobs.
