Submit a PR on GitHub against master if it is approved by one commiter (that did not propose it) it can be merged. The approval is done via the GitHub approval system.
A commiter may create a PR on behalf of a patch submitted to the mailing list.
Commiters can ask for others to review or approve. But at the end of the day they are the ones who approve and merge.
