IDGI. Why do we want this file in uapi?
The DT_ constants are already defined by glibc dirent.h
and the FT_ constants and macros we don't want to expose
to uapi at all. Right?
Maybe all we need is a comment above DT_ constants
that those are defined by POSIX and in glibc dirent.h?

Very trivial code that has had an out of bounds access bug for two
decades and bug was duplicated to 7 filesystems. IMO, fixing the bug in
one place instead of 7 is a good enough reason for re-factoring.
Thanks,
