There will be a v3 anyway where i update the cover latter. The v2 is not
adapted to recently introduced Joel's patch, which is not in linux-next
but will land soon:

Subject: mm/vmalloc: add a safer version of find_vm_area() for debug
Date: Mon, 4 Sep 2023 18:08:04 +0000
It is unsafe to dump vmalloc area information when trying to do so from
some contexts. Add a safer trylock version of the same function to do a
best-effort VMA finding and use it from vmalloc_dump_obj().
<snip>
Also it might come some extra reviews and comments for v2.
Thanks!
