Dan Carpenter reported that:
The patch a955d7eac177: "trace: Add timerlat tracer" from Jun 22,
2021, leads to the following static checker warning:
kernel/trace/trace_osnoise.c:1400 timerlat_main()
warn: inconsistent indenting
here:
1389 while (!kthread_should_stop()) {
1390 now = ktime_to_ns(hrtimer_cb_get_time(&tlat->timer));
1391 diff = now - tlat->abs_period;
1392
1393 s.seqnum = tlat->count;
1394 s.timer_latency = diff;
1395 s.context = THREAD_CONTEXT;
1396
1397 trace_timerlat_sample(&s);
1398
1399 #ifdef CONFIG_STACKTRACE
1400 if (osnoise_data.print_stack)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This should be indented another tab?
1401 if (osnoise_data.print_stack <= time_to_us(diff))
1402 timerlat_dump_stack();
1403 #endif /* CONFIG_STACKTRACE */
1404
1405 tlat->tracing_thread = false;
1406 if (osnoise_data.stop_tracing_total)
1407 if (time_to_us(diff) >= osnoise_data.stop_tracing_total)
1408 osnoise_stop_tracing();
1409
1410 wait_next_period(tlat);
1411 }
And the static checker is right. Fix the indentation.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
