CONFIG_ZSWAP_EXCLUSIVE_LOADS_DEFAULT_ON: Invalidate zswap entries when pages are loaded

General informations

The Linux kernel configuration item CONFIG_ZSWAP_EXCLUSIVE_LOADS_DEFAULT_ON:

• prompt: Invalidate zswap entries when pages are loaded
• type: bool
• depends on: CONFIG_ZSWAP
• defined in mm/Kconfig
• found in Linux kernels: 6.5–6.8

Help text

If selected, exclusive loads for zswap will be enabled at boot, otherwise it will be disabled.

If exclusive loads are enabled, when a page is loaded from zswap, the zswap entry is invalidated at once, as opposed to leaving it in zswap until the swap entry is freed.

This avoids having two copies of the same page in memory (compressed and uncompressed) after faulting in a page from zswap. The cost is that if the page was never dirtied and needs to be swapped out again, it will be re-compressed.
