[LTP] [PATCH v5 3/5] Add fchmodat2 fallback definition

[Petr Vorel]

Hi Andrea,


>  include/lapi/stat.h | 16 ++++++++++++++++
What is the reason this to be added to include/lapi/stat.h?

It's not a general function? (otherwise tst_safe_macros.c would be more
appropriate).

And because one day it will be defined in <sys/stat.h>?

Probably ok due both reasons, but I'm just curious, also because static inline
brought various problems in the past.

The code itself is obviously correct.
