H A Drt-mutex-design.rst220 called pi_lock. This lock may also be taken in interrupt context, so when
221 locking the pi_lock, interrupts must be disabled.
543 On the wake up code, the pi_lock of the current owner is taken. The top
548 Finally we unlock the pi_lock of the pending owner and wake it up.
