Hi Andrew,

As specified in samples/trace_events/Makefile:
If you include a trace header outside of include/trace/events
then the file that does the #define CREATE_TRACE_POINTS must
have that tracer file in its main search path. This is because
define_trace.h will include it, and must be able to find it from
the include/trace directory.
Without this the following compilation error is seen:
CC drivers/soc/qcom/pmic_pdcharger_ulog.o

I never experienced such error, and no CI even reported it, can you explain how you got this ?
To be honest, I am unsure why I'm experiencing this (and until I saw
another thread about it today I thought maybe I had screwed something
up!).
I just took it as an opportunity to try and read up on the tracing
infrastructure and sent this series. Definitely no expertise with the
in's and out's of tracing :)
I'm able to reproduce this on next-20231211:
ahalaney@fedora ~/git/linux-next (git)-[b4/b4-stmmac-handle-mdio-enodev] % ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make mrproper

ahalaney@fedora ~/git/linux-next (git)-[b4/b4-stmmac-handle-mdio-enodev] % ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make defconfig
<snip>
*** Default configuration is based on 'defconfig'
#
# configuration written to .config
#
Realized I missed a step, actually enabling tracing and the driver at
play here... but the result is the same.
Attached is a config where I hit this.

I even tried it in a fedora container with the above build commands and
the following podman invocation (plus some package installs) and saw the error:
podman run -it -v ~/git/linux-next:/linux-next:z quay.io/fedora/fedora:latest /bin/bash
So I'm unsure if it's a fedora package version thing (which I'm running on my host)
or something else... Once I saw it was sort of spelled out in the
examples I referenced here I just decided it was something needed
fixing, regardless of why I'm hitting it while others seem ok.
Interesting, I don't get the problem with the same tag, same .config but with gcc-arm-10.3-2021.07-x86_64-aarch64-none-linux-gnu
I'll try with gcc 13.
Ok tried with ARM's arm-gnu-toolchain-13.2.rel1-x86_64-aarch64-none-linux-gnu (https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads),
and no error, and I even tried with https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/13.2.0/ and same no error...
