Subject: [PATCH] fork: Remove unnecessary size argument when calling strscpy()
Date: Tue, 11 Mar 2025 12:05:39 +0100 [thread overview]
Message-ID: <20250311110542.495630-1-thorsten.blum@linux.dev> (raw)
The size parameter is optional and strscpy() automatically determines
the length of the destination buffer using sizeof() if the argument is
omitted. This makes the explicit sizeof() unnecessary. Remove it to
simplify the code.
