[PATCH 4/4] zcache: promote to drivers/mm/

2012-07-27 Thread Seth Jennings

This patchset promtes the zcache driver from staging to drivers/mm/.

zcache captures swap pages via frontswap and pages that fall
out of the page cache via cleancache and compress them in RAM,
providing a compressed RAM swap and a compressed second-chance
page cache.
