If Lustre was compiled with external OFED but then OFED was removed two modules lnet.ko and ksocklnd.ko will not be able to load but actually they don't depend from OFED functionality.

The second approach can be remove dependency on OFED headers from all code except o2iblnd.
The LNet layer shouldn't refer to anything in the RDMA world directly.
All OFED dependent code should be localized into o2iblnd.

I wonder if this patch would resolve the issue of LU-8352.

Comment by Dmitry Eremin (Inactive) [ 18/Jul/16 ]

I think - no. The header lnet/klnds/o2iblnd/o2iblnd.h:81 still have "#include <libcfs/libcfs.h>".

The http://review.whamcloud.com/21317 patch resolves the issue I reported in LU-8322.
