The meeting notes are linked from the google calendar invitation. If you
want an invitation that also covers all future meetings, just write me a
mail.
In this meeting we'll discuss:
* fbind() and NUMA mempolicy for guest_memfd
* Persisting guest_memfd across reboot / guest_memfs
* guest_memfd use cases for a PFN range allocator
And we'll continue our discussion on:
* Challenges with supporting huge pages
* Challenges with shared vs. private conversion
* guest_memfd as a "library"
