/*
 * The sysctl interface is versioned via the interface_version
 * field. This structures in this header supports sysctl interfaces:
 *
 * - 0x00000008: Xen 4.1
 * - 0x00000009: Xen 4.2
 * - 0x0000000a: Xen 4.3 & 4.4
 * - 0x0000000b: Xen 4.5
 *
 * When adding a new subop be sure to include the variants used by all
 * of the above, both here and in syswrap-xen.c
 *
 * Structs which are identical in all supported versions have no
 * version suffix. Structs which do differ are defined multiple times
 * and use the suffix of the latest version to contain that particular
 * variant.
