[PATCH 1/6 v5] ftrace/x86_64: Rename mcount_64.S to ftrace_64.S Steven Rostedt <rostedt@goodmis.org> - 2017-03-23 15:40 +0100

| Message-ID | <toc4a-3pL-13@gated-at.bofh.it> |
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mcount name is obsolete.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_64.S

x86/ftrace: Rename mcount_64.S to ftrace_64.S
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the mcount name is obsolete.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_64.S and
remove the file name reference.
