Hi again,
I hope I am not harassing you with these patch tests, but I wanted
to have something done before the weekend rest.
But I consider myself more an enthusiast than professional software
developer, let alone the Linux kernel developer. Tester, maybe.
W/o cmdline option ignore_loglevel I get gpio-sim.sh DEVRES trace,
which didn't show in the previous run with the cmdline option on
and attempted "echo 0 > /sys/module/printk/parameters/ignore_loglevel".
I have used the same method of enabling gpio-sim trace in both cases:
[root@...mtodorov gpio]# echo 1 > /sys/kernel/tracing/events/gpio/enable
The output looks like:

Please note that "rmmod gpio-sim" didn't add any new DEVRES entries, if that makes
a difference.
I've been trying to separate the events by running "gpio-sim.sh" at 23:42 and "rmmod gpio-sim" at 23:45,
and the result is evident, but will not delve now into it because I am a bit weather-beaten.
In particular, when comparing to the old test results without the last change:

I hope this helps the big picture.
I hope this redeems me from by Reviewed-by: blunder?
Of course, I realise that I am doing this as a pet project ATM and you might have
professional constraints and reputation to care about I did not consider.
I certainly aim to cling to the Code of Conduct to the fullest. In the academic
sense, appropriating credits where they are due is of utmost importance, too.
I believe that errors and blunders make me authentic :-) It took me time to learn
to live with the fact that I make errors no matter how hard I might try not to.
Best regards,
Mirsad
