From: James Simmons <uja.o...@yahoo.com> Currently the lnet headers used for user land applications contain various kernel definations. This is due to the fact libcfs contains kernel wrappers for user land which will be going away. This patch sorted the header data so all kernel containing structures are moved out of headers that user land will use.
