Your version of this patch series differed from Konrad's "[PATCH v3] Make frontswap+cleancache and its friend be modularized." significantly. In particular, Konrad had four additional patches: Subject: frontswap: remove the check for frontswap_enabled Subject: frontswap: Use static_key instead of frontswap_enabled and frontswap_ops Subject: cleancache: Remove the check for cleancache_enabled. Subject: cleancache: Use static_key instead of cleancache_ops and cleancache_enabled. How come? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
