    cgroup: remove bcache_subsys_id which got added stealthily · add0c59d
    Tejun Heo 提交于
    cafe5635 ("bcache: A block layer cache") added a new cgroup
    subsystem bcache_subsys without proper review and ack.  bcache_subsys
    seems to use cgroup for group stats and per-group cache_mode
    configuration.  This is very much the type of usage that we don't want
    to allow.
    
    Fortunately, CONFIG_CGROUP_BCACHE which enables bcache_subsys is
    currently commented out, so this shouldn't have any upstream users.
    Let's nip in the bud.  While at it, clarify in cgroup_subsys.h that no
    new subsystem should be added without explicit acks from cgroup
    maintainers.
