Subject: [PATCH] mm: Kconfig: fixup zsmalloc configuration
Date: Tue, 3 Sep 2024 13:00:22 +0900 [thread overview]
Message-ID: <20240903040143.1580705-1-senozhatsky@chromium.org> (raw)
zsmalloc is not exclusive to zswap. Commit aa3ba6d72ce0
("mm: Kconfig: fixup zsmalloc configuration") made CONFIG_ZSMALLOC
only visible when CONFIG_ZSWAP is selected, which makes it
impossible to menuconfig zsmalloc-specific features (stats,
chain-size, etc.) on systems that use ZRAM but don't have ZSWAP
enabled.
Make zsmalloc depend on both ZRAM and ZSWAP.
Fixes: Fixes: aa3ba6d72ce0 ("mm: Kconfig: fixup zsmalloc configuration")
