But distros really like to keep it modular. Hmm, we do have obj-$(CONFIG_DASD) += dasd_mod.o obj-$(CONFIG_DASD_DIAG) += dasd_diag_mod.o obj-$(CONFIG_DASD_ECKD) += dasd_eckd_mod.o obj-$(CONFIG_DASD_FBA) += dasd_fba_mod.o Would it work to make CONFIG_DASD built-in only and keep the other 3 as modules? Not sure about the implications.
