Hi,
this post is no bug or patch, but a simple question about the kernel source. Why does do_kern_mount return ENODEV when the given filesystem is unknown? EINVAL seems to be better to me. when i change from ENODEV to EINVAL (fs/super.c:713 in 2.6.0-test10) the following szenario works as i except: kernel options: rootfstype=ext3,ext2 1. load ext2 initrd 2. try to mount as ext3 -> fails (ext3 is a module in my configuration and not in the kernel) 3. try to mount it as ext2 -> fine 4. handle initrd 5. try to mount root as ext3 -> fine (ext3 module now loaded)
the vanilla kernel stops after 2. because some late boot code thinks the initrd is an invalid device (ENODEV).
