Subject: linux-6.17/tools/testing/selftests/landlock/fs_test.c:5631: Test for
 pointer < 0 ?

Hello there,

Static analyser cppcheck says:

linux-6.17/tools/testing/selftests/landlock/fs_test.c:5631:23: style: A pointer can not be negative so it is either pointless or an error to check if it is. [pointerLessThanZero]

Source code is

    if (log_match_cursor < 0)
        return (long long)log_match_cursor;

but

    char *log_match_cursor = log_match;

Suggest remove code.

Regards

David Binderman
