modutils-2.3.21: modprobe looping

Hi Keith,

thanks for your modutils-2.3.21!

During testing I found a problem:
modprobe pppoe was recursing endlessly in build_stack().

Find attached the modules.dep that caused this: There is a circular
dependency of pppoe on pppox on pppoe on ....

modprobe has code to detect this in build_stack(), but it seems to not work.
The old dep is thrown away and the new one is taken. And checked for
dependencies again :-(
Of course, one could also think of depmod making sure that such circular
dependencies do not occur, but I guess, it's more robust if depmod has a
working test in any case.

Test system was a PPC machine running 2.4.0-test9.

Do you have a fix for this?

Regards,
