 * enum transfer_kind - How to send an fd to Trusty

 * @TRUSTY_SHARE: Memory will be accessible by Linux and Trusty. On ARM it will

 *                be mapped as nonsecure. Suitable for shared memory. The paired

 *                fd must be a "memfd".

 * @TRUSTY_LEND:  Memory will be accessible only to Trusty. On ARM it will be

 *                transitioned to "Secure" memory if Trusty is in TrustZone.

 *                This transfer kind is suitable for donating video buffers or

 *                other similar resources. The paired fd may need to come from a

 *                platform-specific allocator for memory that may be

 *                transitioned to "Secure".

 * @TRUSTY_SHARE:       Memory will be accessible by Linux and Trusty. On ARM it

 *                      will be mapped as nonsecure. Suitable for shared memory.

 *                      The paired fd must be a "dma_buf".

 * @TRUSTY_LEND:        Memory will be accessible only to Trusty. On ARM it will

 *                      be transitioned to "Secure" memory if Trusty is in

 *                      TrustZone. This transfer kind is suitable for donating

 *                      video buffers or other similar resources. The paired fd

 *                      may need to come from a platform-specific allocator for

 *                      memory that may be transitioned to "Secure".

 * @TRUSTY_SEND_SECURE: Send memory that is already "Secure". Memory will be

 *                      accessible only to Trusty. The paired fd may need to

 *                      come from a platform-specific allocator that returns

 *                      "Secure" buffers.

 *

 * Describes how the user would like the resource in question to be sent to

 * Trusty. Options may be valid only for certain kinds of fds.
