[PATCH v10 0/4] cgroups: add pids subsystem

This is an updated version of v9 of the pids patchset[1], with a few
small fixes:

* Fixed an off-by-one error in the SUBSYS_TAG macro that affects
intermediate __unused_* values (causing issues when merging tags into
the subsys enum)

* Updated the SUBSYS_TAG macro to be simpler (removed UNUSED_IDENT()
magic) and not use __COUNTER__.

* Removed the SUBSYS_TAG_COUNT macro and replaced it with a hard-coded
CGROUP_PREFORK_COUNT macro.

cgroups: use bitmask to filter for_each_subsys
cgroups: replace explicit ss_mask checking with for_each_subsys_which
cgroups: allow a cgroup subsystem to reject a fork
cgroups: implement the PIDs subsystem
