From: Miaohe Lin Subject: mm/z3fold: declare z3fold_mount with __init Patch series "A few cleanup patches for z3fold", v2. This series contains a few patches to simplify the code, remove unneeded code, fix obsolete comment and so on. More details can be found in the respective changelogs. This patch (of 8): z3fold_mount is only called during init. So we should declare it with __init.
