? Why do you think that?
The 'cs' pointer is dereferenced below without checking, as it is
assumed to always be initialized with
'private->chainstack[smp_processor_id()]'.
+ cs = private->chainstack[smp_processor_id()];
Looks like NULL deref to me. Did you test this?
No, I didn't test this.
Thanks,
