 * To keep the #ifdefery as readable as possible, please:
 *
 * - keep the conditional structure flat, no nesting (e.g. do not fold
 *   the pre-3.11 conditions into the pre-3.14 ones).
 * - group all wrappers for a single kernel revision.
 * - list conditional blocks in order of kernel release, latest first
 * - identify the first kernel release for which the wrapper should
 *   be defined, instead of testing the existence of a preprocessor
 *   symbol, so that obsolete wrappers can be spotted.
