函数名称：group_calc_subtree_ss_mask - calculate subtree_ss_mask*@subtree_control: the new subtree_control mask to consider*@this_ss_mask: available subsystems* On the default hierarchy, a subsystem may request other subsystems to be
函数原型：static u16 cgroup_calc_subtree_ss_mask(u16 subtree_control, u16 this_ss_mask)
返回类型：u16
参数：
| 类型 | 参数 | 名称 |
|---|---|---|
| u16 | subtree_control | |
| u16 | this_ss_mask |
| 1520 | cur_ss_mask等于subtree_control |
| 1528 | 当(true)循环 |
| 1529 | new_ss_mask等于cur_ss_mask |
| 1531 | 循环 |
| 1531 | __ss_mask等于cur_ss_mask |
| 1531 | 如果非CGROUP_SUBSYS_COUNT则 |
| 1531 | 以ssid小于CGROUP_SUBSYS_COUNT循环 |
| 1531 | ss等于cgroup_subsys[ssid] |
| 1533 | 当(false)循环 |
| 1540 | new_ss_mask与等于this_ss_mask |
| 1542 | 如果new_ss_mask恒等于cur_ss_mask则退出 |
| 1544 | cur_ss_mask等于new_ss_mask |
| 1547 | 返回:cur_ss_mask |
