Subject[PATCH -next v7 0/4] Delay the initialization of zswap
Date
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
