Merge tag 'trace-tools-v6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

2023-04-28T23:11:26+00:00

Pull tracing tools updates from Steven Rostedt:

 - Add auto-analysis only option to rtla/timerlat

   Add an --aa-only option to the tooling to perform only the auto
   analysis and not to parse and format the data.

 - Other minor fixes and clean ups

* tag 'trace-tools-v6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:
  rtla/timerlat: Fix "Previous IRQ" auto analysis' line
  rtla/timerlat: Add auto-analysis only option
  rv: Remove redundant assignment to variable retval
  rv: Fix addition on an uninitialized variable 'run'
  rtla: Add .gitignore file

rv: Remove redundant assignment to variable retval

2023-04-25T23:24:28+00:00

Variable retval is being assigned a value that is never read, it is
being re-assigned a new value in both paths of a following if statement.
Remove the assignment.

Cleans up clang-scan warning:
kernel/trace/rv/rv.c:293:2: warning: Value stored to 'retval' is never read [deadcode.DeadStores]
        retval = count;

rv/reactor: remove MODULE_LICENSE in non-modules

2023-04-13T20:13:53+00:00

Since commit 8b41fc4454e ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.

So remove it in the files in this commit, none of which can be built as
modules.

rv: remove redundant initialization of pointer ptr

2023-01-25T15:31:02+00:00

The pointer ptr is being initialized with a value that is never read,
it is being updated later on a call to strim. Remove the extraneous
initialization.

rv/monitors: Move monitor structure in rodata

2022-12-20T16:46:40+00:00

It makes sense to move the important monitor structure into rodata to
prevent accidental structure modification.

rv/monitors: add 'static' qualifier for local symbols

2022-09-26T17:01:09+00:00

The sparse tool complains as follows:

kernel/trace/rv/monitors/wwnr/wwnr.c:18:19:
warning: symbol 'rv_wwnr' was not declared. Should it be static?

The `rv_wwnr` symbol is not dereferenced by other extern files,
so add static qualifier for it.

So does wip module.

rv/monitors: Make monitor's automata definition static

Monitor's automata definition is only used locally, so make
them static for all existing monitors.
