Hugh's looking into this. > https://lkml.kernel.org/r/759077a6-a08-5bb0-a0b6-53be2fe8b56a@xxxxxxxxxx Yes, thanks Dan: Yu Zhao already reported, the fix I sent was https://lore.kernel.org/linux-mm/7a4f5e5e-de33-dace-c526-4a3d3cf5f6e0@xxxxxxxxxx/ but it hasn't got into mm-unstable yet. I've not yet digested Kirill's review comments on the series (no functional change required, I believe): maybe they will call for a v2 rather than a series of -fixes; but let's add the above in for now. Thanks, Hugh
