You seemed to have completely ignored my last review (for instance
https://sourceware.org/pipermail/libc-alpha/2021-August/129961.html),
so I won't bother to spent time checking on this version. 

All of them were done on August [1] and I have even sent a message
added that I fixed fixed the issues I found [2] (I also sent a private
email about it).

Anyway, if someone else want to review this version fell free.
