This is kernel log clutter.

You can ask the kernel for the list of interfaces, and
use even ethtool to ask what driver each interface is
associated with.

The patch wasn't applied because it really is not necessary.
I disagree completely. I'm working right now on a udev-based system that
does ethernet device renaming. It's quite difficult when working with
udev to tell exactly when and why each interface was renamed, since it's
typically done within initramfs where it's difficult to enable debug
messages. This printk helps immensely.

You can listen on a netlink socket for these events if you
want to see when they occur.

Unfortunately that's not very practical if, as in this case, the renaming is being done from an initramfs. Hiding this information as we do now is rather user-hostile.


There is no need for this log message, it is superfluous.

I think the minimal extra output from this is well worth it. If we care so much about limiting dmesg output, how about getting rid of all those hundreds of "PM: Adding info for" messages in recent kernels..
