OK, I am now horridly confused. If you prefer "mm/z3fold.c: fix z3fold_buddy_slots use after free" then why did you send me "mm/z3fold: don't try to use buddy slots after free"? Also, I assume that "the compaction patch" is "z3fold: add inter-page compaction"? That patch was dropped on July 1, which is rather a long time ago. It still applies (with a single trivial reject) on "mm/z3fold: don't try to use buddy slots after free", so what's the problem? For reference, there are presently four z3fold patches in -mm: https://ozlabs.org/~akpm/mmots/broken-out/mm-z3foldc-lock-z3fold-page-before-__setpagemovable.patch https://ozlabs.org/~akpm/mmots/broken-out/mm-z3foldc-lock-z3fold-page-before-__setpagemovable-fix.patch https://ozlabs.org/~akpm/mmots/broken-out/mm-z3foldc-dont-try-to-use-buddy-slots-after-free.patch https://ozlabs.org/~akpm/mmots/broken-out/mm-z3foldc-remove-z3fold_migration-trylock.patch
