Because you'd have to write (CGROUP_TAG_END - CGROUP_TAG_START) every
time? It's a small addition and it makes referencing

Hi,
Do you also want me to completely drop the COUNT macro? IMO it makes
the CGROUP__COUNT consolidation much nicer.

Add a new cgroup subsystem callback can_fork that conditionally
states whether or not the fork is accepted or rejected by a cgroup

occurs later in the forking process, any state modified by can_fork can
be reverted.
