Subject: [PATCH 4/7] net: Replace get_task_comm() with %pTN
Date: Fri, 13 Dec 2024 13:46:07 +0800	[thread overview]
Message-ID: <20241213054610.55843-5-laoar.shao@gmail.com> (raw)
In-Reply-To: <20241213054610.55843-1-laoar.shao@gmail.com>

Since task->comm is guaranteed to be NUL-terminated, we can print it
directly without the need to copy it into a separate buffer. This
simplifies the code and avoids unnecessary operations.
