Subject: [PATCH 0/2] rtmutex: Lockless reader wake + explicit check for TASK_RTLOCK_WAIT.

This is a follow up to
  https://lkml.kernel.org/r/87wnnjcuam.ffs@tglx

While forming the patch, I got currious why the state check is against
TASK_RTLOCK_WAIT and against TASK_NORMAL. So I swapped to to
TASK_RTLOCK_WAIT which should be more robust.
