Subject: [PATCH 0/3] mm: remove zpool
Date: Fri, 29 Aug 2025 17:15:25 +0100 [thread overview]
Message-ID: <20250829162212.208258-1-hannes@cmpxchg.org> (raw)
zpool is an indirection layer for zswap to switch between multiple
allocator backends at runtime. Since 6.15, zsmalloc is the only
allocator left in-tree, so there is no point in keeping zpool around.
Based on mm-everything-2025-08-29-00-23.
