Subject[PATCH -next v9 0/3] 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.

v8->v9: Fix some pattern problem suggested by Christoph.
v7->v8: Do some cleanup. And remove the second patch in v7 which is unrelated
to the initialization of zswap.
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 (3):
mm/zswap: remove zswap_entry_cache_{create,destroy} helper function
mm/zswap: replace zswap_init_{started/failed} with zswap_init_state
mm/zswap: delay the initialization of zswap
