111  * TEE_IOC_SHM_ALLOC - allocate shared memory
113  * Allocates shared memory between the user space process and secure OS.
117  * The returned file descriptor is used to map the shared memory into user

201  * Shared memory is allocated with TEE_IOC_SHM_ALLOC which returns an
202  * identifier representing the shared memory object. A memref can reference
203  * a part of a shared memory by specifying an offset (@a) and size (@b) of
