[PATCH] Shut up about the damn modules already...

[Rusty Russell <rusty@rustcorp.com.au>]

Please apply before 2.6.3.

In almost all distributions, the kernel asks for modules which don't
exist, such as "net-pf-10" or whatever.  Changing "modprobe -q" to
"succeed" in this case is hacky and breaks some setups, and also we
want to know if it failed for the fallback code for old aliases in
fs/char_dev.c, for example.

Just remove the debugging message which fill people's logs: the
correct way of debugging module problems is something like this:

echo '#! /bin/sh' > /tmp/modprobe
echo 'echo "$@" >> /tmp/modprobe.log' >> /tmp/modprobe
echo 'exec /sbin/modprobe "$@"' >> /tmp/modprobe
chmod a+x /tmp/modprobe
echo /tmp/modprobe > /proc/sys/kernel/modprobe

Thanks!
Rusty.
