FYI, today's draft of this ioctl can be read here:
https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git/commit/?h=health-monitoring_2026-01-13&id=e3fee7d7ead8b3e630845304b9030b5c7c5f27da

It contains all the alterations I talked about earlier today.

(I might be coming down with a cold, so I thought it best to git push
now and find out if I'm at all coherent tomorrow.)
