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?
