@astrojuanlu @mmayo You don't need to have merge rights to make valuable contributions.
Sure, in some cases @Gargron might not accept contributions, but the same is true of paid contributor to lots of other major open source projects; there are lots of folks who do kernel work full time, who have patch series rejected and need to either rewrite or drop it.
Even if patches aren't accepted upstream, they may be accepted for local forks or widely used forks like glitch-soc.
@unlambda @astrojuanlu @Gargron I'm with @unlambda this is open source, changes might be interesting upstream or they might not be that's ok.
