Three Kconfig symbols are introduced: CONFIG_INFINIBAND_RMR (silent, selected by either side) CONFIG_INFINIBAND_RMR_CLIENT (depends on INFINIBAND_RTRS_CLIENT) CONFIG_INFINIBAND_RMR_SERVER (depends on INFINIBAND_RTRS_SERVER) The Makefile builds two modules: rmr-client.ko and rmr-server.ko, sharing the pool, map, request and library code added earlier in this series.
