It looks to me like this:
static void rdma_init_coredev(struct ib_core_device *coredev,
struct ib_device *dev, struct net *net)
{
coredev->dev.groups = dev->groups;
^^^^^^^^^^^^^^^^^^^^^
Copies the sysfs groups from the normal ib_dev which includes the hw_*
stuff to the per-NS device?
Everything in that groups list must use rdma_device_to_ibdev()
int ib_setup_device_attrs(struct ib_device *ibdev)
{
[..]
attr->attr.show = hw_stat_device_show;
attr->show = show_hw_stats;
data->group.attrs[pos] = &attr->attr.attr;
[..]
ibdev->groups[i] = &data->group;
Which means the sysfs reported here is in that list?
Maybe this was misses when the sysfs was shut off?
