Also, formatting other lines with indent makes " A newly allocated path. The
memory is freed automatically at the end" to be bold. The correct formatting is
therefore without indent:

/**
 * tst_tmpdir_path - Returns a pointer to a tmpdir path.
 *
 * The returned path is allocated and initialized the first time this function is
 * called, each subsequent call will return the same pointer.
 *
 * return: A newly allocated path. The memory is freed automatically at the end
 * of the test. If allocation fails the function calls tst_brk() and
 * exits the test.
 */
char *tst_tmpdir_path(void);

/**
 * tst_tmpdir_mkpath - Construct an absolute path pointing to a file inside tmpdir.
 *
 * Constructs a path inside tmpdir i.e. adds a prefix pointing to the current
 * test tmpdir to the string build by the printf-like format.
 *
 * @fmt: A printf-like format string.
 * @...: A printf-like parameter list.
 *
 * return: A newly allocated path. The memory is freed automatically at the end
 * of the test. If allocation fails the function calls tst_brk() and exits the
 * test.
 */
char *tst_tmpdir_mkpath(const char *fmt, ...)
	__attribute__((format(printf, 1, 2)));


Kind regards,
