Aww. I thought it was a nice patch, but my foresight was inadequate.
The problem I tried to fix was related to strncmp used in the code which
supported __setup(). Our installer, Anaconda, recognizes both "nousb" and
"nousbstorage" - in theory. In practice, passing "nousbstorage" switched
USB completely off because of improper strncmp(). If we back out my patch,
this problem is going to reoccur.
We might want to ask Jeremy Katz if "nousbstorage" is even used anymore,
then revert all this if not. Or, we can add a name somehow and live
with it visible in sysfs...
