Hi,
what is the task state of some processes/threads that are in a deadlock
situation? I've heard about TASK_UNINTERRUPTIBLE. Is not it?
In a deadlock situation both tasks are waiting for a resource that is
held by another task, therefore none of the other tasks waiting for that
resource can proceed. In TASK_INTERRUPTIBLE/TASK_UNINTERRUPTIBLE the
task is in a sleeping state with the exception that TASK_UNINTERRUPTIBLE
cannot be woken up by a signal. So it seems a deadlock can occur with a
task in an interruptible or uniterruptible state.
