From: Arnd Bergmann <arnd@xxxxxxxx> The mlx5_ib_fs_add_op_fc/mlx5_ib_fs_remove_op_fc functions are only available when user access is enabled, without that we run into a link error: ERROR: modpost: "mlx5_ib_fs_add_op_fc" [drivers/infiniband/hw/mlx5/mlx5_ib.ko] undefined! ERROR: modpost: "mlx5_ib_fs_remove_op_fc" [drivers/infiniband/hw/mlx5/mlx5_ib.ko] undefined! Conditionally compiling the newly added code section makes it build, though this is probably not a correct fix.
