Subject: [PATCH -next v6 0/2] Delay the initialization of zswap
Date: Wed, 22 Mar 2023 18:20:04 +0800 [thread overview]
Message-ID: <20230322102006.780624-1-liushixin2@huawei.com> (raw)
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
