Ick. First a few general comments on procedure:
- please CC: linux-hotplug devel, or linux-kernel with core stuff like
this.
- your patch was line-wrapped, and could not be applied :(
- No Signed-off-by: line as per the rules specified in
Documentation/SubmittingPatches.
Ok, now, what exactly are you trying to solve here? With 2.6.14 and
udev handling the hotplug control, you should not see any need for a
change like this.
thanks,
