[LTP] [PATCH] open07: Convert to new API

[Petr Vorel]

Hi Martin,

Reviewed-by: Petr Vorel <pvorel@suse.cz>

Few minor things below, can be fixed before merge.

...
>  #define _GNU_SOURCE		/* for O_NOFOLLOW */
nit: This now works without _GNU_SOURCE (we compile with -std=gnu99 and it would
work for whatever gnu*).

> -#include <stdio.h>
> -#include <errno.h>
> -#include <sys/types.h>
>  #include <sys/stat.h>
nit: IMHO <sys/stat.h> was not needed even in the old API version.

nit: any reason for -1? (We don't check the input.)

nit: IMHO this is not needed (we have 0 for stdin, right? Therefore open()
should not get 0 and check below is correct).

Kind regards,
Petr
