I pointed it out to make clear that there are licensing problems and ambiguities if one strictly insists that #include some_gpl.h implies that the code is GPL'd. If that is the case, then there are MUCH bigger licensing problems than LSM, so don't take it up with me, either :-)

Since revisions to the kernel's GPL are explicitly prohibited, it seems to me that this statement of one side of the controversy as if it were a fact increases confusion rather than decreases it.

"This file is GPL. See the Linux Kernel's COPYING file for details. There is controversy over whether this permits you to write a module that #includes this file without placing your module under the GPL. Consult your lawyer for advice."
I'm really trying to be constructive here. There is a real licensing problem over whether binary modules are legitimate at all, and the issue is not special to LSM. I'm trying to get LSM out of the way so that the advocates of either side can fight it out without smushing LSM in the middle :-)
