Thanks for the report!
Yes, I think I messed it up again by changing both fstatat and
fstat. Our internal names in the kernel are a bit inconsistent
and I failed to realize that only newfstatat uses the "new" name
in the user-facing macro.

Right, I should have done that before the original series really:
I spent a lot of time validating the kernel's internal changes for
consistency (which found a dozen bugs that were unrelated to my
series) but missed the unintended changes to the external header
contents.
I'll do that now and send another fixup.
