    Description

      Building against a recent kernel the -Werror option in the Rules file is catching a re-definition of CONFIG_LNET_MAX_PAYLOAD and causing the build to fail.

            All patches for Ubuntu15 support have landed. This ticket reported the same problems as LU-5628 so it can be now closed as a duplicate.

            I have submitted all the patches needed to support Ubuntu15 now. With those patches also kernels up to 4.0 are supported.

            Colin do you have a gerrit account so I can add you to review the patches needed.

            I have submitted a bunch of patches for Ubuntu15 support. Only thing left is handle filldir_t api changes and generic_file_aio_XX changes.

            Yep, its the tip of the iceberg. If you want to build the intel branch against 4.1-rc1 you will a bunch more patches just to make it work. See LU-6215 for details about that work.

            The problem at hand is you probably have lustre configured i nthe kernel as a module or something, and this is not supported due to all sort of symbol clases, I suspect this is just a tip of the iceberg you are seeing here.

            If you want to build out of tree lustre, the in-tree lustre client should be disabled.
