Subject: jjb: lttng-modules: split gerrit jobs by branch
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=3da11679b413e19bf7bd6081c8f228a076e196c7;p=lttng-ci.git

jjb: lttng-modules: split gerrit jobs by branch

This allows to set kernel version ranges per branch. Also now build on
each current head of the kernel tls branches and the head of the latest
supported kernel branch.
