Let's do it for the general FS shrinker (super_block::s_shrink) and mark it as memcg aware. There are other FS-specific shrinkers that use list_lru for storing objects, such as XFS and GFS2 dquot cache shrinkers, but since they reclaim objects that may be shared among different cgroups, there is no point making them memcg aware.
