Yeah, this failure is from the kmemleak stack which simply means that
debugging tool will be disabled rather than any disruption to the
workflow.
I'm curious why kmemleak is masking with GFP_KERNEL and GFP_ATOMIC and not
allowing users to pass __GFP_NOWARN to suppress this type of failure,
especially since the stack trace is already emitted by kmemleak when it is
stopped. Catalin?

Indeed, is there a reason why the kmemleak code is so noisy? And can
it display a more obvious message about what is going on? It took me
a while to figure out why it was unhappy, and whether there it was a
fault of the code it was testing, or just that it could get the memory
it needed....

Good point, I think kmemleak can always pass __GFP_NOWARN for its own
allocations. Note that these allocations are only for the kmemleak
metadata, the other users just allocate memory with the flags they
requested. When failing, it could also avoid printing call traces
(maybe keep a debug macro in case one wants to track this).
I'll post a patch on Monday.
Thanks.
