I don't recall you reporting that, sorry.

The warning was added by

: commit 82f682514a5df89ffb3890627eebf0897b7a84ec
: Author:     James Bottomley <james.bottom...@suse.de>
: AuthorDate: Mon Jul 5 22:53:06 2010 +0200
: Commit:     Rafael J. Wysocki <r...@sisk.pl>
: CommitDate: Mon Jul 19 02:00:34 2010 +0200
: 
:     pm_qos: Get rid of the allocation in pm_qos_add_request()


It's a pretty crappy warning too.  Neither the warning nor the code
comments provide developers with any hint as to what they have done
wrong, nor what they must do to fix things.  And the patch changelog
doesn't mention the new warnings *at all*.

So one must assume that the people who stuck this thing in the tree
have volunteered to fix e1000e.  Let's cc 'em.
