Subject: [RFC][PATCH 1/5] x86/ftrace: Rename mcount_64.S to ftrace.S
Date: Wed, 15 Mar 2017 15:55:28 -0400	[thread overview]
Message-ID: <20170315200254.777780858@goodmis.org> (raw)
In-Reply-To: 20170315195527.703131481@goodmis.org

[-- Attachment #1: 0001-x86-ftrace-Rename-mcount_64.S-to-ftrace.S.patch --]
[-- Type: text/plain, Size: 1670 bytes --]

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

With the advent of -mfentry that uses the new "fentry" hook over mcount, the
mcount name is obsolete. Having the code file that ftrace hooks into called
"mcount*.S" is rather misleading. Rename it to ftrace.S
