Hi Thomas,

This series from Dmitry is at v7:

https://lore.kernel.org/lkml/cover.1747817128.git.dvyukov@google.com/

The initial version from February 2025 can be found here:

https://lore.kernel.org/lkml/ffd123bb0c73df5cdd3a5807b360bd390983150b.1739790300.git.dvyukov@google.com/

What are the next steps to get it upstream ? We have not heard back
from the tip tree maintainers since June 2025 after repeated pings
from Dmitry.

Note: it will likely conflict with your rseq rework.

Thanks,

Mathieu
