	And I appreciate it; I just wanted to make sure our many fans
following along at home didn't misunderstand.

	Could you let me know if the patch below make the lockdep
warning go away?  This applies on top of the previous three, although it
should be trivial to do by hand.

	I'm still checking to make sure this is safe with regard to
mutexing the bonding structures, but it would be good to know if it
eliminates the warning.
