Hi Jens,

Zsmalloc has two methods 1) copy-based and 2) pte-based to access
allocations that span two pages. You can see history why we supported
two approach from [1].
In summary, copy-based method is 3 times fater in x86 while pte-based
is 6 times faster in ARM.

I'll add that and test...
I'm curious. Does your code grab a read lock? If you grab the same
