rdtgroup_size

函数名称：dtgroup_size_show - Display size in bytes of allocated regions* The "size" file mirrors the layout of the "schemata" file, printing the* size in bytes of each region instead of the capacity bitmask.

函数原型：static int rdtgroup_size_show(struct kernfs_open_file *of, struct seq_file *s, void *v)

返回类型：int

参数：

类型	参数	名称
struct kernfs_open_file *	of
struct seq_file *	s
void *	v
