Subject: [RFC][PATCH v5 08/51] objtool: mcount: Remove unused fname parameter
Date: Thu, 18 Jun 2020 13:37:54 -0700 [thread overview]
Message-ID: <93aeffe2e6529cf01f5238d1342af6d5206fd85d.1592510545.git.mhelsley@vmware.com> (raw)
In-Reply-To: <cover.1592510545.git.mhelsley@vmware.com>
The name of the object file being processed is unused in
the wrapper's leaf functions so we no longer need to pass
it as a parameter.
