+Subject: PCI/IB: add support for pci driver attribute groups
+
+Some drivers (specifically the nes IB driver), want to create a lot of
+sysfs driver attributes.  Instead of open-coding the creation and
+removal of these files (and getting it wrong btw), it's a better idea to
+let the driver core handle all of this logic for us.
+
+So add a new field to the pci driver structure, **groups, that allows
+pci drivers to specify an attribute group list it wishes to have created
+when it is registered with the driver core.
+
+Big bonus is now the driver doesn't race with userspace when the sysfs
+files are created vs. when the kobject is announced, so any script/tool
+that actually wanted to use these files will not have to poll waiting
+for them to show up.
