I was somewhat surprised that this patch got merged. I think Russell had some objections to it (he would've preferred to see it use page-granular allocations and hence avoid the need to switch to u64). But since it's already landed in Linus' tree and this fix in v4.0-rc4 I guess it'd be too much churn to back it out again. Thierry
