9b8eb69886 Apparently sampled call stacks may be empty. 2020-03-28 16:09:44 +01:00

6c0c508280 Ignore kernel-only stacks.
It is common to receive duplicate stack traces for the same timestamp
(and thread), one containing proper user-space stack, and the second one
containing only kernel frames. Discard the second one, as there's no
documentation how this should be interpreted and the kernel stack is
mostly useless.

sampling.
