Subject: [PATCH -next v6 0/2] Delay the initialization of zswap

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.

v5->v6: Simplify the code and delete the patches about frontswap suggested
	by Christoph.

Liu Shixin (2):
  mm/zswap: skip invalid or unchanged parameter
  mm/zswap: delay the initializaton of zswap
