That's your preference not mine.

I added netdev_<level> and netif_<level>.

You are not the driver maintainer and those decisions
are driver maintainer decisions not yours.

Check this out:

$ grep -rP -oh --include=*.[ch] \
	"\b[a-z]+_(dbg|alert|crit|emerg|notice|warn|err|info)\b\s*\(" drivers | \
  sed -e 's/(//g' -r -e 's/\s*//g' | \
  sort | uniq | wc -l
266

Most all of those are different logging forms.

So, not crazy, just not your preference.

I've put in some effort trying to standardize logging
messages and mechanisms as well, and I think

	<prefix>_<level>(struct *, fmt, ..._

is a perfectly good and understandable style.

I do not suggest using some arbitrary prefix just for the
sake of it, only when there is a specific structure that
can be used.

cheers, Joe


==================================

I am adding Alan Cox, Mark Gross, and Bruce Beare into the discussion.

I will not do anything to change the logging in this driver until I get
better clarification from Mark, Alan, and Bruce as well as Greg.

Thanks
