Based on the recent discussion on the core reviewers shortage and the proposals from the email thread (Proposal: Changes in Core Reviewer discussion at TSC):
"If you are an active member of this community and have confidence in your knowledge of the code in one or more parts of the system, please volunteer to be a new Core Reviewer by posting on this mailing list. The other Cores will be very grateful."

Also, if it is really required, I could help with the starlingx/utilities repo, owning the "pci-irq-affinity-agent" code that is mainly used by stx-openstack application and with which I've worked before.
