These addresses the performance issues reported by Matt, Namhyung and Linus. Recently it changed processing comm string and DSO with sorted arrays but it required to sort the array whenever it adds a new entry. This caused a performance issue and fix is to enhance the sorting by finding the insertion point in the sorted array and to shift righthand side using memmove().
