Any feedback on this patch?.
Thanks,

Please don't top post when you are responding on kernel
mailing lists. It gets very difficult to follow the
comments in the email thread.

Hi,
Yes, I did install the latest kernel headers and TASK_COMM_LEN is not
accessible in userspace.
I looked into the test which uses TASK_COMM_LEN but the test defines
it in its own header file.
Example: https://elixir.bootlin.com/linux/latest/source/tools/testing/selftests/bpf/progs/pyperf.h#L13
bfp test does things differently because its dependencies
on run-time environment.
TASK_COMM_LEN is defined in include/linux/sched.h, but this header
file is not exposed to userspace.
Correct. you can include linux/sched.h like other tests do
Take a look at tools/testing/selftests/clone3
You are right about TASK_COMM_LEN not visible to user-space.
This patch has been applied to linux-kselftest next for 6.6-rc1
thanks,
