Hi Andrea, Cyril,

9120d8a22 ("safe_macros: turn functions with off_t parameter into static inline")
noted:

    Some functions used to implement safe macros have parameters
    of type off_t or structures containing off_t fields.

These functions (safe_mmap(), safe_stat(), safe_lstat(), ...) are
therefore below this comment:

/*
 * following functions are inline because the behaviour may depend on
 * -D_FILE_OFFSET_BITS=64 compile flag
 */

But IMHO that's not the case for safe_prot_to_str(), or am I missing
something? It does not use any struct, thus no off_t. And what about
safe_mprotect() (added in the same commit).

If I'm correct, I would prefer to move it (+ other functions added in
9120d8a22 to lib/tst_safe_macros.c and keep here only their signatures.

First, it document properly what depends on -D_FILE_OFFSET_BITS=64,
second, this approach to avoid static inline in headers started by
Martin Doucha is IMHO cleaner.

Kind regards,
Petr
