Is there an easier way to do this? As an addendum to the steps I described in my last post, it's possible that in your particular case that the ioctl-related data structures in user space are also "known" by the kernel, i.e. structures that are common to both user-space and kernel-space. If that's true, then you don't need the "add-symbol-file" step -- just make sure that you are in the crash context of the process that owns the user-space instance, determine the user-space address of the structure, and simply use the "struct -u" option.
