This is the same patch I sent for v3.2.9-rt17. (where you complained
because I gave clark a SOB instead of a Tested-by:) I see that
#define preempt_check_resched()
without the _rt has been shuffled to a more logical spot which is the
only way I recognized that you mean this for v3.0.23-rt.

Could we please start to specify the rt-kernel version in these patches?

Thanks

John
