So, are you saying the identifier will be found in a distro release package (like a "linux-headers" package or something similar) but *not* found in the Ubuntu linux-source-x.y.z package even after doing some level of processing of the source in that package? If that is the case, we will have to also load the Ubuntu linux-headers-x.y.z-n package into our LXR database if we want to be able to find the identifier to make Ubuntu-specific changes to our driver code. ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
