   5  * The sysctl interface is versioned via the interface_version
   6  * field. This structures in this header supports sysctl interfaces:
   7  *
   8  * - 0x00000008: Xen 4.1
   9  * - 0x00000009: Xen 4.2
  10  * - 0x0000000a: Xen 4.3 & 4.4
  11  * - 0x0000000b: Xen 4.5
  12  *
  13  * When adding a new subop be sure to include the variants used by all
  14  * of the above, both here and in syswrap-xen.c
  15  *
  16  * Structs which are identical in all supported versions have no
  17  * version suffix. Structs which do differ are defined multiple times
  18  * and use the suffix of the latest version to contain that particular
  19  * variant.
