So let's figure out what happens with this patch.
I'm personally ok with the change, the question is when
and where.

My net-2.6 tree was closed to new features long ago, so I really
don't want to try to merge this sucker into 2.6.28-rcX :-)  But if
you guys think that is prudent, feel free to submit it directly to
Linus and add my signoff:

Signed-off-by: David S. Miller <davem@davemloft.net>

otherwise if we shoot for 2.6.29 I would suggest that we wait until
the merge window to see if the sysfs issues get sorted, and if not
we slip this patch into to tree instead.

Let me know what you guys plan to do with this.
