FYI, a regression introduced by this commit was reported by s390x
glibc developers testing against linux-next:

https://sourceware.org/pipermail/libc-alpha/2025-January/163993.html

I've sent a fix here:

https://lore.kernel.org/lkml/20250116205956.836074-1-mathieu.desnoyers@xxxxxxxxxxxx/

The commit introducing the issue is in this PR, but not the fix.

Thanks,

Mathieu
