Subject: [RFC PATCH 2/4] objtool: Enable objtool to run only on files with ftrace enabled
Date: Mon, 23 May 2022 23:25:46 +0530 [thread overview]
Message-ID: <20220523175548.922671-3-sv@linux.ibm.com> (raw)
In-Reply-To: <20220523175548.922671-1-sv@linux.ibm.com>
This patch makes sure objtool runs only on the object files
that have ftrace enabled, instead of running on all the object
files.
