[-- Attachment #1: 0001-tracing-Rename-trace-ftrace.h-to-trace-trace_events..patch --]
[-- Type: text/plain, Size: 52374 bytes --]
From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
The name "ftrace" really refers to the function hook infrastructure. It
is not about the TRACE_EVENT() macros. The file trace/ftrace.h was originally
written to be mostly focused toward the "ftrace" code (that in kernel/trace/)
but ended up being generic and used by perf and others.
Rename the file to be less confusing about what infrastructure it belongs to.

[-- Type: text/plain, Size: 22479 bytes --]
From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
The trace_event.h file is for the generic trace event code. Move
the perf related code into its own trace header file perf.h

[-- Attachment #1: 0003-tracing-Rename-ftrace_event.h-to-trace_events.h.patch --]
[-- Type: text/plain, Size: 46632 bytes --]
From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
The term "ftrace" is really the infrastructure of the function hooks,
and not the trace events. Rename ftrace_event.h to trace_events.h to
represent the trace_event infrastructure and decouple the term ftrace
from it.

[-- Attachment #1: 0004-tracing-Rename-ftrace_print_-functions-ta-trace_prin.patch --]
[-- Type: text/plain, Size: 7817 bytes --]
From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
The name "ftrace" really refers to the function hook infrastructure. It
is not about the trace_events. The functions ftrace_print_*() are not part of
the function infrastructure, and the names can be confusing. Rename them
to be trace_print_*().

[-- Attachment #1: 0005-tracing-Rename-un-register_ftrace_event-to-un-regist.patch --]
[-- Type: text/plain, Size: 9947 bytes --]
From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
The name "ftrace" really refers to the function hook infrastructure. It
is not about the trace_events. The functions (un)register_ftrace_event() is
really about trace_events, and the name should be register_trace_event()
instead.
Also renamed ftrace_event_reg() to trace_event_reg() for the same reason.

[-- Attachment #1: 0007-tracing-Rename-ftrace_event_-call-class-to-trace_eve.patch --]
[-- Type: text/plain, Size: 57695 bytes --]
From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
The name "ftrace" really refers to the function hook infrastructure. It
is not about the trace_events. The structures ftrace_event_call and
ftrace_event_class have nothing to do with the function hooks, and are
really trace_event structures. Rename ftrace_event_* to trace_event_*.

[-- Attachment #1: 0008-tracing-Rename-ftrace_event_buffer-to-trace_event_bu.patch --]
[-- Type: text/plain, Size: 4563 bytes --]
From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
The name "ftrace" really refers to the function hook infrastructure. It
is not about the trace_events. The ftrace_event_buffer functions and data
structures are for trace_events and not for function hooks. Rename them
to trace_event_buffer*.

[-- Attachment #1: 0009-tracing-Rename-ftrace_output-functions-to-trace_outp.patch --]
[-- Type: text/plain, Size: 6141 bytes --]
From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
The name "ftrace" really refers to the function hook infrastructure. It
is not about the trace_events. The ftrace_output_*() and ftrace_raw_output_*()
functions represent the trace_event code. Rename them to just trace_output
or trace_raw_output.

From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
The name "ftrace" really refers to the function hook infrastructure. It
is not about the trace_events. Rename the max trace_event type size to
something more descriptive and appropriate.

From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
The name "ftrace" really refers to the function hook infrastructure. It
is not about the trace_events. ftrace_event_name() returns the name of
an event tracepoint, has nothing to do with function tracing. Rename it
to trace_event_name().

[-- Attachment #1: 0012-tracing-Rename-struct-ftrace_subsystem_dir-to-trace_.patch --]
[-- Type: text/plain, Size: 8165 bytes --]
From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
The name "ftrace" really refers to the function hook infrastructure. It
is not about the trace_events. The structure ftrace_subsystem_dir holds
the information about trace event subsystems. It should not be named
ftrace, rename it to trace_subsystem_dir.

[-- Attachment #1: 0013-tracing-Rename-FTRACE_EVENT_FL_-flags-to-EVENT_FILE_.patch --]
[-- Type: text/plain, Size: 17819 bytes --]
From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
The name "ftrace" really refers to the function hook infrastructure. It
is not about the trace_events. The FTRACE_EVENT_FL_* flags are flags to
do with the trace_event files in the tracefs directory. They are not related
to function tracing. Rename them to a more descriptive name.

[-- Attachment #1: 0014-tracing-Rename-ftrace_trigger_soft_disabled-to-trace.patch --]
[-- Type: text/plain, Size: 4015 bytes --]
From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
The name "ftrace" really refers to the function hook infrastructure. It
is not about the trace_events. The ftrace_trigger_soft_disabled() tests if a
trace_event is soft disabled (called but not traced), and returns true if
it is. It has nothing to do with function tracing and should be renamed.

The name "ftrace" really refers to the function hook infrastructure. It
is not about the trace_events. The ftrace_raw_##call structures are built
by macros for trace events. They have nothing to do with function tracing.
Rename them.

From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
The name "ftrace" really refers to the function hook infrastructure. It
is not about the trace_events. The structure ftrace_data_offset_##call is
used to find the offsets of dynamically allocated fields in trace_events.
It has nothing to do with function tracing. Rename it.

I compiled each patch individually and did some smoke testing. No
problems found so far. I don't know if that already classifies for the
Tested-by tag, though feel free adding it.

Thanks, but it has already been added to linux-next, which means no
more rebasing for adding tags :-/
One of my tests (done with ktest) that I do before adding anything
to linux-next is to test each patch individually to make sure it doesn't
add any new warnings or errors, and boots, and also runs a smoke test.
