This deviation was discussed and agreed upon during the review process of the zsmalloc writeback patch series:
https://lore.kernel.org/lkml/[email protected]/ Unfortunately, this introduces a subtle bug that occurs when there is a concurrent store and reclaim, which interleave as follows:
zswap_frontswap_store() shrink_worker() zs_malloc() zs_zpool_shrink() spin_lock(&pool->lock) zs_reclaim_page() zspage = find_get_zspage() spin_unlock(&pool->lock) spin_lock(&pool->lock) zspage = list_first_entry(&pool->lru) ---truncated--- (CVE-2023-54165)
