函数名称：dtgroup_kn_mode_restore - Restore user access to named resctrl file*@r: The resource group with which the file is associated.*@name: Name of the file*@mask: Mask of permissions that should be restored* Restore the permissions of the named file

函数原型：int rdtgroup_kn_mode_restore(struct rdtgroup *r, const char *name, umode_t mask)

返回类型：int

参数：

类型	参数	名称
struct rdtgroup *	r
const char *	name
umode_t	mask

1570

struct iattr iattr = {ia_valid = Attribute flags. These should be or-ed together to figure out what* has been changed!, }

1575

rfts等于dtgroup information files for one cache resource.

1576

len等于ARRAY_SIZE - get the number of elements in array @arr*@arr: array to be sized(dtgroup information files for one cache resource. )

1578

以rft小于rfts加len 循环

1579

如果非字符串比较则ia_mode等于mode按位与mask

1583

kn等于kernfs_find_and_get_ns(kn, name, NULL)

1584

如果非kn则返回:负ENOENT

1588

当:kernfs_type(kn)恒等于KERNFS_DIR

1589

parent等于kernfs_get_parent(kn)

1590

如果parent则

1591

ia_mode或等于mode

1592

kernfs_put(parent)

1594

ia_mode或等于S_IFDIR

1595

退出

1596

当:kernfs_type(kn)恒等于KERNFS_FILE

1597

ia_mode或等于S_IFREG

1598

退出

1599

当:kernfs_type(kn)恒等于KERNFS_LINK

1600

ia_mode或等于S_IFLNK

1601

退出

1604

ret等于kernfs_setattr(kn, & iattr)

1605

kernfs_put(kn)

1606

返回:ret
