[Lldb-commits] [PATCH] D144904: [Linux] Add kernel.yama.ptrace_scope note when ptrace fails to attach.

DavidSpickett added a comment.

And testing would require the test to `sudo ...` so I don't think this can be tested.

+        "fail to attach to a running process. To fix this, run:\n"
----------------
Tell me if I understand correctly. This error is only used if you've already failed to attach. So if you had a value of 1 or 2, but attaching worked fine, you wouldn't see this.

Which is why you've said "which can cause" instead of "does cause". As there are some situations with 1 or 2 that do work.
