Comment # 4 on bug 1231416 from Jiri Slaby

I intend also to disable Z3FOLD. Which means not only
CONFIG_ZSWAP_ZPOOL_DEFAULT_Z3FOLD_DEPRECATED=n but also
CONFIG_Z3FOLD_DEPRECATED=n. So the current setup (x86_64):

CONFIG_ZPOOL=y
CONFIG_SWAP=y
CONFIG_ZSWAP=y
# CONFIG_ZSWAP_DEFAULT_ON is not set
# CONFIG_ZSWAP_SHRINKER_DEFAULT_ON is not set

# CONFIG_ZSWAP_COMPRESSOR_DEFAULT_DEFLATE is not set
CONFIG_ZSWAP_COMPRESSOR_DEFAULT_LZO=y
# CONFIG_ZSWAP_COMPRESSOR_DEFAULT_842 is not set
# CONFIG_ZSWAP_COMPRESSOR_DEFAULT_LZ4 is not set
# CONFIG_ZSWAP_COMPRESSOR_DEFAULT_LZ4HC is not set
# CONFIG_ZSWAP_COMPRESSOR_DEFAULT_ZSTD is not set
CONFIG_ZSWAP_COMPRESSOR_DEFAULT="lzo"

# CONFIG_ZSWAP_ZPOOL_DEFAULT_ZBUD is not set
# CONFIG_ZSWAP_ZPOOL_DEFAULT_Z3FOLD_DEPRECATED is not set
CONFIG_ZSWAP_ZPOOL_DEFAULT_ZSMALLOC=y
CONFIG_ZSWAP_ZPOOL_DEFAULT="zsmalloc"

CONFIG_ZBUD=y
# CONFIG_Z3FOLD_DEPRECATED is not set
CONFIG_ZSMALLOC=y
# CONFIG_ZSMALLOC_STAT is not set
CONFIG_ZSMALLOC_CHAIN_SIZE=8


And I pushed this to my master/for-next.
