Hi Leon,

After I sent my email I discovered the following commit: 5ead723a20e0
("lib/vsprintf: no_hash_pointers prints all addresses as unhashed"; v5.12).
I think that commit does what we need?

Thanks Bart,

I agree.

Jason, as to traces, I suspect we need to do the same %p thing there for existing code and any new work.

For situations for debugging in the wild, a command line arg can show the actual value. I'm ok with that.


Can this patch which changes %llx to %p in infiniband hfi1 to avoid kernel pointer release be applied?
