A built-in SMB file system cannot link against a modular infiniband core module:
fs/cifs/smbdirect.o: In function `smbd_destroy_rdma_work': smbdirect.c:(.text+0x28e3): undefined reference to `ib_drain_qp' smbdirect.c:(.text+0x2915): undefined reference to `rdma_destroy_qp' smbdirect.c:(.text+0x2d08): undefined reference to `ib_free_cq' smbdirect.c:(.text+0x2d3d): undefined reference to `ib_free_cq' smbdirect.c:(.text+0x2d6f): undefined reference to `ib_dealloc_pd' smbdirect.c:(.text+0x2d9a): undefined reference to `rdma_destroy_id' fs/cifs/smbdirect.o: In function `smbd_disconnect_rdma_work': smbdirect.c:(.text+0x3d3e): undefined reference to `rdma_disconnect' fs/cifs/smbdirect.o: In function `_smbd_get_connection': smbdirect.c:(.text+0x5bc2): undefined reference to `rdma_create_id' smbdirect.c:(.text+0x5cc5): undefined reference to `rdma_resolve_addr' smbdirect.c:(.text+0x5cda): undefined reference to `rdma_destroy_id' smbdirect.c:(.text+0x5da7): undefined reference to `rdma_destroy_id' smbdirect.c:(.text+0x5e89): undefined reference to `rdma_resolve_route' smbdirect.c:(.text+0x5f07): undefined reference to `rdma_destroy_id'
This changes the Kconfig dependency to enforce selecting one of the valid configurations.
