Hi!
> This NUMA API doesn't not attempt to implement page migration or anything

> is first allocation or when a page is reallocated after swapping. Currently
> only support for shared memory and anonymous memory is there; policy for
> file based mappings is not implemented yet (although they get implicitely
> policied by the default process policy)

> set_mempolicy to change the policy of a process, get_mempolicy to retrieve
> memory policy. User tools (numactl, libnuma, test programs, manpages) can be
set_mempolicy is pretty ugly name. Why is prctl inadequate?
