Daniel Wagner b6139a6abf lib/group_cpus: Let group_cpu_evenly() return the number of initialized masks ... group_cpu_evenly() might have allocated less groups then requested: group_cpu_evenly() __group_cpus_evenly() alloc_nodes_groups() # allocated total groups may be less than numgrps when # active total CPU number is less then numgrps In this case, the caller will do an out of bound access because the caller assumes the masks returned has numgrps. Return the number of groups created so the caller can limit the access range accordingly.
