This series allows for CONFIG_INFINIBAND without CONFIG_INFINIBAND_ADDR_TRANS (aka RDMA communication manager). Fuzzing has been finding fair number of CM bugs. So provide an option to disable it in systems which don't need it. Changes since last posting (https://lkml.org/lkml/2018/4/25/1266): - added ("ib_srp: depend on INFINIBAND_ADDR_TRANS") patch This series passed the 0-day builder. I perfomed manual static analysis of this series based on next-20180424, looking for dependencies. $ git grep -w CONFIG_INFINIBAND_ADDR_TRANS drivers/infiniband/core/Makefile:infiniband-$(CONFIG_INFINIBAND_ADDR_TRANS) := rdma_cm.o drivers/infiniband/core/Makefile:user_access-$(CONFIG_INFINIBAND_ADDR_TRANS) := rdma_ucm.o $ grep -w -e rdma_cm -e rdma_ucm drivers/infiniband/core/Makefile infiniband-$(CONFIG_INFINIBAND_ADDR_TRANS) := rdma_cm.o user_access-$(CONFIG_INFINIBAND_ADDR_TRANS) := rdma_ucm.o rdma_cm-y := cma.o rdma_cm-$(CONFIG_INFINIBAND_ADDR_TRANS_CONFIGFS) += cma_configfs.o rdma_ucm-y := ucma.o $ grep EXPORT drivers/infiniband/core/{cma,ucma}.c drivers/infiniband/core/cma.c:EXPORT_SYMBOL(rdma_event_msg);
