// IOCTLs supporting exclusive CSPI access between OAL and all device drivers.
//
// Note that we must specify OAL_IOCTL_FLAG_NOCS to avoid using a critical
// section during the CSPI lock/unlock IOCTL calls. Otherwise, we can deadlock
// the system if we also happen to block while within the IOCTL call because
// we cannot immediately acquire the CSPI lock (which is another critical
// section).
