110  * Allocates shared memory between the user space process and secure OS.
114  * The returned file descriptor is used to map the shared memory into user

198  * Shared memory is allocated with TEE_IOC_SHM_ALLOC which returns an
199  * identifier representing the shared memory object. A memref can reference
