| |
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
