Unless I misunderstood something, the zombie task (called actuatorTask)
does not appear in /proc/xenomai/sched and /proc/xenomai/stat, the task
which appears there is "Actuator Aperiodic Task". actuatorTask, however,
appears in the sysrq+T output, and its state (for Linux scheduler, not
for xenomai scheduler, since for xenomai scheduler it does not even
exist) is "?", so, what I would like to know is its real state, printed
in hexadecimal. For this, you just have to print p->state using 0x%08x
as printk format.
