Rule 5.3 has the following headline: "An identifier declared in an inner scope shall not hide an identifier declared in an outer scope" The renaming s/sched_id/scheduler_id of the function defined in 'xen/common/sched/core.c' prevents any hiding of that function by the many instances of omonymous function parameters. Similarly, the renames - s/ops/operations - s/do_softirq/exec_softirq - s/loop/it are introduced for parameter names, to avoid any conflict with the homonymous variable or function defined in an enclosing scope.
