But there's a huge difference in the other parts of that same file where GFP_ACCOUNT is _not_ used. I think this unification is too small to bother with. Something I've had on my todo list for some time and have not done anything about is to actually unify all of the architecture pte/pmd/... allocations. There are tricks some architectures use that others would benefit from. _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
