Subject: [PATCH net-next] net/sched: Remove redundant memset(0) call in reset_policy()
Date: Mon, 11 Aug 2025 18:40:38 +0200 [thread overview]
Message-ID: <20250811164039.43250-1-thorsten.blum@linux.dev> (raw)
The call to nla_strscpy() already zero-pads the tail of the destination
buffer which makes the additional memset(0) call redundant. Remove it.
