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

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