The Slurm developers and support at SchedMD will only consider patches from their paying customers, and only consider non-customers in exceptional cases. Therefore your patch may have a hard time getting attention.
One clarification - SchedMD does look at contributions from everyone. Our contributing guide describes the process:
https://gitlab.com/SchedMD/dev/slurm/-/blob/master/CONTRIBUTING.md
I'll admit that there are a lot of submissions that I don't respond to publicly after initial triage. This is usually as the patch is either overly specific to the submitter's own system, or isn't addressing the issue appropriately.
The notable difference in routing between customer-submitted patches and community contributions is that I will usually redirect patches back to support for further discussion and triage.
