Are I2C drivers "critical stuff"? What about AHCI drivers? What about all the USB HCI drivers? USB Storage can certainly be loaded from an initramfs, yet it's =y. LED triggers? Loads of RTC drivers that are marked as =y? XOR drivers? VIRTIO drivers? Filesystems? I seem to remember Red Hat sets even popular filesystems to be a module in their kernel. Clearly, "defconfig=y is only for critical stuff" is rather false in practice, and I suspect is little more than a desire rather than a rule. I suspect it's more "defconfig=y is for stuff that makes most platforms successfully boot without an initramfs". -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last! _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
