cgroup: remove bcache_subsys_id which got added stealthily
cafe563591 ("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.
