TaiJu Wu 23d65cb97f shced:sem: replace mutex with spinlock ... The overhead of spinlok is less than mutext (mutex need to call enter_critical section.) After this patch, `down_write_trylock` and `down_read_trylock` can be use in interrupt context. The instruction is protected with mutex only one instruction so using spinlock is better.
