Hi David,

The kernel uses open code to check if a process is in root PID namespace or not in several places.
Suggested by Suzuki, this patch set is to create a helper function task_is_in_init_pid_ns() to replace open code.
This patch set has been applied on the mainline kernel and built for Arm64 kernel with enabling all relevant modules.
I'd like sync for how to merging this patch set. Except patch 05/07, all of other patches in this patch set have been received the reviewed or acked tags. So could you pick up this patch set?
Furthermore, we have another patch set "coresight: etm: Correct PID tracing for non-root namespace" [1], which is dependent on the current patch set and it has been Acked by Suzuki.
I'd like to get opinions from David and CoreSight maintainers Mathieu and Suzuki, should we merge the patch set [1] via David's tree as well to avoid dependency issue, or prefer to merge it via CoreSight tree? If David prefers the prior option, I can resend the patch set [1] with looping David.
Thanks, Leo
