Thanks. I'd prefer to defer this until the next -rc cycle
(https://lkml.kernel.org/r/20260323202941.08ddf2b0411501cae801ab4c@linux-foundation.org).
If Ulad would prefer that we push ahead then OK.
Are we able to describe how much memory this change might save under
various scenarios? If the savings are impressively large then that
would get attention.
AI review might have found a couple of things, one pre-existing:
