Hey! Good point.
I ran the custom kernel for a couple days without issue. 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?</pre>
