[LTP] [PATCH v3 3/5] Add fchmodat2 fallback definition

[Petr Vorel]

Hi Andrea,

IMHO more consistent is:
static inline int fchmodat2(int dfd, const char *filename, mode_t mode, int flags)

But more important, you need to have as first two params: const char *file,
const int lineno, e.g.:

#define SAFE_FCHMODAT2(path, mode) \
	safe_access(__FILE__, __LINE__, (filename), (mode), (flags))

static inline int fchmodat2(const char *file, const int lineno, int dfd, const
	    char *filename, mode_t mode, int flags)
{
...
#

This way instead of this:
../../../../include/lapi/stat.h:239: TBROK: fchmodat2(3,symlink,416,256) error: EOPNOTSUPP (95)
we get file and line of the test (common approach, see lib/tst_safe_macros.c
include/tst_safe_macros.h).

Kind regards,
Petr
