In-Reply-To: <20261025181125.514372-9-atomlin@atomlin.com>
> Add an automated unit test suite ("Ftrace inline processing") in

> Uses vmlinux_path__find() to locate the kernel image, setting up
> symbol resolution and validating activate_task inlining within
> wake_up_new_task at offset 0x1d1.
>
> 2. Inline presentation and return address filtering
>
> Verifies that synthesised inlined entries and exits are
> [ ... ]
> FTRACE_MAX_STACK capacity.
