    cpumask: Partition_sched_domains takes array of cpumask_var_t · acc3f5d7
    Rusty Russell authored
    Currently partition_sched_domains() takes a 'struct cpumask
    *doms_new' which is a kmalloc'ed array of cpumask_t.  You can't
    have such an array if 'struct cpumask' is undefined, as we plan
    for CONFIG_CPUMASK_OFFSTACK=y.
    
    So, we make this an array of cpumask_var_t instead: this is the
    same for the CONFIG_CPUMASK_OFFSTACK=n case, but requires
    multiple allocations for the CONFIG_CPUMASK_OFFSTACK=y case.
    Hence we add alloc_sched_domains() and free_sched_domains()
    functions.
