If Andy wants to change the symbol of what he wrote from EXPORT_SYMBOL_GPL() to EXPORT_SYMBOL(), that's fine, it's his option. Any loony discussion about if this is actually a licensing issue or not needs to just go to /dev/null As homework, everyone please go read this: http://softwarefreedom.org/resources/2014/SFLC-Guide_to_GPL_Compliance_2d_ed.pdf and remember that the license of the Linux kernel is GPLv2. Now where's the "kill this thread" option on mutt so I don't have to see any more of this nonsense... greg k-h
