Dan Carpenter reported that: The patcha955d7eac1: "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.
