    Subject[RFC] NUMA aware kthread_create() ?
    Hi

    Is there any plans about making a kthread_create_on_cpu() version of
    kthread_create(), so that memory allocated for thread stack/info is allocated
    on the node of the target CPU ?

    There is a mention about kthread_create_on_cpu() in a comment in
    include/linux/kthread.h, but no implementation.

    The current use pattern is

    p = kthread_create(ksoftirqd, hcpu, "ksoftirqd/%d", hotcpu);
    if (IS_ERR(p)) { error ... }
    kthread_bind(p, hotcpu);

    So the thread memory is currently allocated on the node of the current cpu, ie
    not the target cpu (hotcpu in this example)

    Thank you
    Eric Dumazet
