168 * swapon tell device that all the old swap contents can be discarded,
169 * to allow the swap device to optimize its wear-levelling.
238 * swap allocation tell device that a cluster of swap can now be discarded,
239 * to allow the swap device to optimize its wear-levelling.
371 * Determine the locking method in use for this device. Return
1280 * Check whether swap entry is valid in the swap device. If so,
1282 * via preventing the swap device from being swapoff, until

1376 * Caller has made sure that the swap device corresponding to entry
1474 * Sort swap entries by swap device, so each lock is only taken once.
