Building UCM with CONFIG_INFINIBAND_USER_ACCESS=m results in a set of link errors including: drivers/infiniband/core/ucm.o: In function `ib_ucm_event_handler': ucm.c:(.text+0x6dc): undefined reference to `ib_copy_path_rec_to_user' drivers/infiniband/core/ucma.o: In function `ucma_event_handler': ucma.c:(.text+0xdc0): undefined reference to `ib_copy_ah_attr_to_user' To get it to build-test again, this makes the option itself a tristate, which lets Kconfig figure out the dependency correctly.
