| |
Hi Ingo, Oleg,
sched.h has a comment in task_struct
volatile long state; /* -1 unrunnable, 0 runnable, >0 stopped */
After some searching, I've not been able to figure out how state can become -1 (or unrunnable). Can you let me know how that happens?
If it cannot reach that state, then maybe this patch is needed.
