Yes, please do send that patch on to Linus for 3.3. It did not get as much as the 36 hours of testing I had hoped for, only 25 hours so far. 12 hours while I was out yesterday got wasted by a wireless driver interrupt spewing approximately one million messages: iwl3945 0000:08:00.0: MAC is in deep sleep!. CSR_GP_CNTRL = 0xFFFFFFFF which I've not suffered from before, and hope not again. Having kdb in, I did take a look what was going on with the memcg load when it was interrupted: it appeared to be normal, and I've no reason to suppose that my kfree_rcu() was in any way responsible for the wireless aberration.
