Here is my suggestion on how to proceed. 1. Let's drop this patch (memcg: cache obj_stock by memcg, not by objcg pointer) from mm-tree. 2. Let's not add anything to 7.1. 3. 7.2+ will have the multi-objcg series [1] and the patches will have fixes tag. If someone uses non-LTS 7.1, they can easily find those patches and can backport them. Please let me know if there are any concerns. [1] https://lore.kernel.org/20260522011908.1669332-1-shakeel.butt@linux.dev/
