Is there a sensible way to couple them? I don't see much, except opencode
VM_BUG_ON():
if (IS_ENABLED(CONFIG_DEBUG_VM) && cond) {
dump_page(...);
dump_vma(...);
dump_whatever();
BUG();
}
That's too verbose to me to be usable.
BTW, I also tried[1] to solve this problem too, but people doesn't like
either.
