Greetings fellow crash users. The hacklet below keeps crash working
(for the nonce) into the 5.14 kernel cycle. I doubt it's applicable (despite being kinda sorta disguised as a patch just in case;), but it should serve as a bandaid until the real deal comes along.
Handle kernel rename of task_struct.state to __state
Kernels post 5.13 renamed task->state to task->__state. Check the
validity of 'state', and upon failure, rashly presume that "__state"
exists, and isn't going to change again any time soon.
