Subject: [PATCH net-next] net: Space: Replace memset(0) + strscpy() with strscpy_pad()
Date: Thu, 14 Aug 2025 20:05:14 +0200 [thread overview]
Message-ID: <20250814180514.251000-2-thorsten.blum@linux.dev> (raw)
Replace memset(0) followed by strscpy() with strscpy_pad() to improve
netdev_boot_setup_add(). This avoids zeroing the memory before copying
the string and ensures the destination buffer is only written to once,
simplifying the code and improving efficiency.
