From 16d78e8cda8b4447812f375480c8cb780f396c1e Mon Sep 17 00:00:00 2001 From: Xu Panda Date: Thu, 5 Jan 2023 20:17:57 +0800 Subject: rcu/trace: use strscpy() to instead of strncpy() This commit saves a line of code by switching from strncpy() to strscpy() by permitting the later NUL assignment to be removed. While in the area, save another line by taking advantage of 100 characters. Acked-by: Joel Fernandes (Google) Signed-off-by: Xu Panda Signed-off-by: Yang Yang Signed-off-by: Paul E.
