The 2023 Maintainers Summit will be held on November 16 in Richmond, VA,
immediately after the Linux Plumbers
Conference.

As in previous years, the Maintainers Summit is invite-only, where
the primary focus will be process issues around Linux Kernel
Development. It will be limited to 30 invitees and a handful of
sponsored attendees.

The call for
topics has just gone out, with the first invitations to be sent within
a couple of weeks or so.
