In the initialization of zswap, about 18MB memory will be allocated for zswap_pool. Since some users may not use zswap, the zswap_pool is wasted. Save memory by delaying the initialization of zswap until enabled.
v6->v7: Add two new patch[1,3] to cleanup the code. And cover zswap_init_* parameter by zswap_init_lock to protect against conflicts. v5->v6: Simplify the code and delete the patches about frontswap suggested by Christoph.
Liu Shixin (4): mm/zswap: remove zswap_entry_cache_{create,destroy} helper function mm/zswap: skip invalid or unchanged parameter mm/zswap: replace zswap_init_{started/failed} with zswap_init_state mm/zswap: delay the initializaton of zswap
