okay, as it seems, I cannot recreate this here
please could you make the following changes to
get_task_state()
static inline const char * get_task_state(struct task_struct *tsk)
{
unsigned int state;
BUG_ON(!tsk);
state = (tsk->state & (TASK_RUNNING |
TASK_INTERRUPTIBLE |
TASK_UNINTERRUPTIBLE |
TASK_STOPPED |
TASK_TRACED |
TASK_ONHOLD)) |
(tsk->exit_state & (EXIT_ZOMBIE |
EXIT_DEAD));
const char **p = &task_state_array[0];
while (state) {
p++;
state >>= 1;
}
BUG_ON(!p);
return *p;
}
TIA,
Herbert
