Hi,
In backports, we have the following spatch:
@ attribute_group @
identifier group;
declarer name ATTRIBUTE_GROUPS;
@@
ATTRIBUTE_GROUPS(group);
@ class_group depends on attribute_group @
identifier group_class;
identifier groups;
fresh identifier group_dev_attr = attribute_group.group ## "_dev_attrs";
@@
struct class group_class = {
+#if LINUX_VERSION_CODE >= KERNEL_VERSION(3,11,0)
.dev_groups = groups,
+#else
+ .dev_attrs = group_dev_attr,
+#endif
};
[...]
But this isn't sufficient and falls over if there are multiple
instances of ATTRIBUTE_GROUPS, it's essentially undefined which one
gets picked.
I tried to match a modified identifier like this:
@ attribute_group @
identifier group;
fresh identifier groups = group ## "_groups";
declarer name ATTRIBUTE_GROUPS;
@@
ATTRIBUTE_GROUPS(group);
@ class_group depends on attribute_group @
identifier group_class;
identifier attribute_group.groups;
fresh identifier group_dev_attr = attribute_group.group ## "_dev_attrs";
@@
struct class group_class = {
+#if LINUX_VERSION_CODE >= KERNEL_VERSION(3,11,0)
.dev_groups = groups,
+#else
+ .dev_attrs = group_dev_attr,
+#endif
};
[...]
but that doesn't work at all.
Any thoughts?
