Linus Torvalds a3fe778c78 Frontswap provides a "transcendent memory" interface for swap pages. ... In some environments, dramatic performance savings may be obtained because swapped pages are saved in RAM (or a RAM-like device) instead of a swap disk.

In some environments, dramatic performance savings may be obtained because swapped pages are saved in RAM (or a RAM-like device) instead of a swap disk. This tag provides the basic infrastructure along with some changes to the existing backends." Fix up trivial conflict in mm/Makefile due to removal of swap token code changing a line next to the new frontswap entry. This pull request came in before the merge window even opened, it got delayed to after the merge window by me just wanting to make sure it had actual users. Apparently IBM is using this on their embedded side, and Jan Beulich says that it's already made available for SLES and OpenSUSE users. Also acked by Rik van Riel, and Konrad points to other people liking it too. So in it goes.
