From: Rob Landley <rob@landley.net> I usually use UML as a better fakeroot, meaning I run it with a command line like "rootfstype=hostfs rw quiet init=/path/to/some_shell_script.sh". In this context, filling the screen with parse_chan_pair error messages which don't actually hurt anything defeats the purpose of adding "quiet". The patch turns several KERN_ERR into KERN_WARNING. While I was there, I merged the redundant printk() statements into a function, and added an "else" after a test-for-null that did a printk but didn't do a continue.
