cgroup: make cgroup_calc_subtree_ss_mask() take @this_ss_mask
cgroup_calc_subtree_ss_mask() currently takes @cgrp and
@subtree_control. @cgrp is used for two purposes - to decide whether
it's for default hierarchy and the mask of available subsystems. The
former doesn't matter as the results are the same regardless. The
latter can be specified directly through a subsystem mask.
This patch makes cgroup_calc_subtree_ss_mask() perform the same
calculations for both default and legacy hierarchies and take
@this_ss_mask for available subsystems. @cgrp is no longer used and
dropped. This is to allow using the function in contexts where
available controllers can't be decided from the cgroup.
v2: cgroup_refres_subtree_ss_mask() is removed by a previous patch.
Updated accordingly.
