Can I use WdfRequestRetrieveInputBuffer to get the EA buffer for a create?
The buffer is in the
Irp->AssociatedIrp.SystemBuffer but it looks like I need to decode the IRP?
Just wanted to check before going there.

No you cannot use WdfRequestRetrieveInputBuffer. You have to decode the Irp
(you can get EaLength from WDF_REQUEST_PARAMETERS though).
