I honestly don't care if there's a dump_stack or not. I just removed the
WARN_ON. If the allocation causes a dump_stack() then that's fine, but
I still like to have a bit more information at what failed to allocate,
than just a offset into a function.

The point of this patch was simply to remove WARN_ON() that caused
fuzzers to fail.
