Yes! The line wrap.


                if (kmem_cache_debug(s)
                || cpu_slab_objects + cpu_partial_objects >
s->max_cpu_object / 2)
                        break;

Above example use 82 columns... The line wrapping problem.

                if (kmem_cache_debug(s) ||
                cpu_slab_objects + cpu_partial_objects > s->max_cpu_object / 2)
                        break;

This one use 79 columns, but somehow ugly
because second line start at same column of above line.
Is it okay?

                                                > s->max_cpu_object / 2)
                        break;

Is it the best?
It use 72 columns.
Let me know what is the best method for this situation.

Thanks!
