Re: task state in a deadlock

[Vincenzo Mallozzi <vinjunior@xxxxxxxx>]

Is there a deterministic way to know if a process is in deadlock have state 
TASK_INTERRUPTIBLE or TASK_UNINTERRUPTIBLE? 
I really need this information to know if some threads are in such a 
situation.
How can I resolve this problem? Is there another solution?

Thanks.
Vincenzo
