Benjamin Walsh 168695c7ef kernel/arch: inspect prio/sched_locked together for preemptibility ... These two fields in the thread structure control the preemptibility of a thread. sched_locked is decremented when the scheduler gets locked, which means that the scheduler is locked for values 0xff to 0x01, since it can be locked recursively. A thread is coop if its priority is negative, thus if the prio field value is 0x80 to 0xff when looked at as an unsigned value. By putting them end-to-end, this means that a thread is non-preemptible if the bundled value is greater than or equal to 0x0080. This is the only thing the interrupt exit code has to check to decide to try a reschedule or not.
