Hi Suraj,

if (frame->fp == (unsigned long)task_pt_regs(tsk)->stackframe)
	return -ENOENT;

If I understand correctly, a similar final frame check is introduced in this patch:

arm64: Implement stack trace termination record
https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git/commit/?id=7d7b720a4b80


It is currently merged into for-next/stacktrace branch.


Thanks & Best Regards,
