Subject: [PATCH 2/3] staging:lustre: remove kernel defines in userland headers
From: James Simmons <uja.ornl@...oo.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.
