Hi, I just tried to build a system that uses jffs on /dev/mtdblock0 as root fs. This didn't work right away because the kernel did not honor the option "root=/dev/mtdblock0" . This is because mtdblock devices are not listed in the list of known root devices in the kernel (see "root_dev_names" in file init/main.c). After applying the attached patch, using mtdblock as rootfs worked nicely. Now my question is: is there any particular reason (other than "nobody has told Linus") why this is not already in the standard kernel ? If there isn't, should I go ahead and submit my patch to Linus ?
