unresolved symbol in 2.4.1 depmod.

[Jason Michaelson]

Greetings. I've just procured myself a copy of 2.4.1, and tried to build
it. At the tail end of a make modules_install, the following error occurs:

depmod: *** Unresolved symbols in /lib/modules/2.4.1/kernel/drivers/md/md.o
depmod:         name_to_kdev_t

My first assumption was that this occurred because I'm running 2.2.15 with
a collection of patches. Except I've never seen this happen before with
upgrades.

Thanks,

jdm

name_to_kdev_t is defined in init/main.c.  It is not exported so it
cannot be called from modules.  name_to_kdev_t *cannot* be exported
because it is defined as __init, the code has gone by the time the
module is loaded.  Ask the md maintainer for a fix.

How did this used to work, then?  The call to name_to_kdev_t has been
in the md code since (according to the code comments) May, 2000; the
module worked fine as of 2.4.1-pre10, which is the last version I used.

It might have worked as built in code, I would be astounded if it ever
worked as a module on a standard kernel after that code was added.
name_to_kdev_t has been defined as this since at least 2.4.0-test1.

kdev_t __init name_to_kdev_t(char *line)

You cannot export a symbol marked __init and expect it to work.
