Would you like me to do some more testing? I went back to vanilla 4.18-rc7 - but I'd be happy to make my daily driver 4.18-rc7 with the patch. My understanding is that kvmalloc is a slightly safer way of allocating memory as compared to kmalloc - in that it doesn't necessarily need the memory to be contiguous. The downside is that it's not quite a performant. Is this correct?
