Subject: [PATCH] ftrace: Use within_module to check rec->ip within specified module.
Date: Thu, 3 Aug 2023 21:52:36 +0100 [thread overview]
Message-ID: <20230803205236.32201-1-ppbuk5246@gmail.com> (raw)
within_module_core && within_module_init condition is same to
within module but it's more readable.
Use within_module instead of former condition to check rec->ip
within specified module area or not.
