Hi all!
I was able to to use linux (2.4.x and 2.5.x) on a floppy with busybox using
this great devfs only, which saves me lots of spaces. I use the initial ram
disk.
But since I downloaded linux-2.5.29, nothing worked anymore.
Then I came a long about the problem with ramdisk driver and applied the
patch.
To my surprise :) it worked again. I was able to boot again.
As I tried to mount the boot floppy I got instead my floppy(ext2), driverfs
mounted??? How can that be? I'll send you my boot-floppy image, if you ask
me for that.
---------------------------------------------------------
I did the following:
without file system type specified:
# mount /dev/floppy/0 /mnt
**** driverfs is mounted instead of my ext2-floppy
# mount
...
/dev/floppy/0 on /mnt type driverfs (rw)
with file system type specified:
# mount -t ext2 /dev/floppy/0 /mnt
**** I got the following kernel dump
generic_make_request: Trying to access nonexistent block-device fd(2,0) (0)
Unable to handle kernel NULL pointer dereference at virtual address 000000a0
...
...
floppy0: timeout handler died: floppy shutdown
-----------------------------------------------------------
I have "Kernel automounter version 4 support" compiled in.
Would someone, who has enough time to "break" some linux-API behaviour, also
has time to notes this down!
Maybe there should be a kind of separate "WARNING_API_CHANGED" file under
Documentation, so that everybody might keep up with the latest "What might
be broken now?".
cheers,
-sE

Thanks for your information. Did that, and found your patch.
Tried it, but no luck ;( (as noted in your README.txt)
Nevertheless, this idea:
>> Maybe there should be a kind of separate "WARNING_API_CHANGED" file under

might reduce "noises" in LKML and might save bits and bandwidth.
Best regards,
