The only thing that confused me was if and when we need to use the
plural form of the key names.
We need to use the plural form whenever we want udev to search up the
device tree to make a match. If (for instance) we're only interested in
the subsystem value for the device udev is looking at, we can use
SUBSYSTEM="xyz". But if we want to match all devices hooked up to a PCI
bus, directly or indirectly, we have to have it walk the tree. (No, I'm
not sure why we'd want to do this. But that's OK. ;-) )
OK, that was my initial understanding too, but I had the same doubt as
you as to why we'd want to walk the tree, hence I assumed I was in need
of a cluebat :-)
3) 26-modprobe.rules: Replace ATTR{...} with ATTRS{...} everywhere;
SYSFS searched up before, so we should probably keep doing that, just in
case it's required.
Would you believe that the initial version of my patch used ATTRS? As
per my confusion outlined above I convinced myself that ATTR would be
good enough!
Oh, and I left contrib/ alone. Once the rule_generator rules go in,
I guess that directory can be removed, right?
Yeah, looks that way.
Great. Thanks very much for the quick and detailed response, Bryan.
Feel free to commit your patch, or I'll pick it up tonight.
Regards,
Matt.
