    Subject[PATCH 0/3] have pooled sunrpc services make more intelligent allocations
    The sunrpc code has had some support for spreading pooled services over
    different NUMA nodes and CPUs for some time. So far though, this support
    has been for CPU masks only. Memory allocated for these services is
    generally done by whatever CPU happens to be running the init script
    that starts the services and so most of it ends up on the same NUMA node.
    This means that nfsd's end up wasting a lot of time updating remote
    memory on a different memory node.

    This patchset attempts to remedy that by having pooled services make
    per-thread allocations that are on their local memory node. I have no
    hard performance numbers for this particular patchset, but Greg Banks
    sent me a different patch that has a similar effect and claims that
    there is a significant performance gain.

    Comments and suggestions appreciated...
