函数名称：rdtgroup_rmdir

函数原型：static int rdtgroup_rmdir(struct kernfs_node *kn)

返回类型：int

参数：

类型参数名称
struct kernfs_node *kn
2975  parent_kn等于* Use kernfs_get_parent() and kernfs_name/path() instead of * accessing the following two fields directly. If the node is * never moved to a different parent, it is safe to access the * parent directly.
2978  ret等于0
2980  如果非zalloc_cpumask_var( & tmpmask, GFP_KERNEL)则返回:负ENOMEM
2983  rdtgrp等于rdtgroup_kn_lock_live(kn)
2984  如果非rdtgrp则
2985  ret等于负EPERM
2986  转到:out
2996  如果type恒等于RDTCTRL_GROUP且parent_kn恒等于kn则
2997  如果mode恒等于RDT_MODE_PSEUDO_LOCKSETUP或mode恒等于RDT_MODE_PSEUDO_LOCKED则
2999  ret等于rdtgroup_ctrl_remove(kn, rdtgrp)
3000  否则
3001  ret等于rdtgroup_rmdir_ctrl(kn, rdtgrp, tmpmask)
3003  否则如果type恒等于RDTMON_GROUP且We allow creating mon groups only with in a directory called "mon_groups"* which is present in every ctrl_mon group. Check if this is a valid* "mon_groups" directory.* 1. The directory should be named "mon_groups".* 2则
3005  ret等于rdtgroup_rmdir_mon(kn, rdtgrp, tmpmask)
3006  否则
3007  ret等于负EPERM
3010  out :
3011  rdtgroup_kn_unlock(kn)
3012  释放CPU掩码
3013  返回:ret
