Would you please fix your broken mail agent (quilt?), it appears to be putting 
in a blank line above what you see above, which is the convention for end of 
header, beginning of body, so all the people you've included above, including 
the lkml, are actually getting this as private mail due to header parsing 
ending prematurely.
