Good! I will do that. Thanks for clarifying the irq and constraints on raw locks in the other thread.
Are there any suggestions for "now"? preempt_disable_nort() like Luis suggesed?
The preempt_disable_nort() is rather pointless, because the preempt_disable() was added specifically for -rt. When PREEMPT_RT is not enabled, preemption is disabled there already by the previous calls to spin_lock().
