Subject: Re: [PATCH 3/6] mm, memcg: Prevent memory.low load/store tearing

Hi Michal,

Good catch! Andrew and I must have missed these when massaging the commits with 
other stuff in -mm, which is totally understandable considering the amount of 
places being touched by this and other patch series at the same time. Just goes 
to show how complex it can be sometimes, since I even double checked these and 
didn't see that missed hunk :-)

The good news is that these are belt-and-suspenders: this avoids a rare 
theoretical case, not something likely to be practically dangerous. But yes, we 
should fix it up. Since the commit is already out, I'll just submit a new one.

Thanks for the report!

Chris
