#     
#     Pull perf tools fixes from Namhyung Kim:
#      "Fix performance issue for v6.10
#     
#       These address the performance issues reported by Matt, Namhyung and
#       Linus. Recently perf changed the processing of the comm string and DSO
#       using sorted arrays but this caused it to sort the array whenever
#       adding a new entry.
#     
#       This caused a performance issue and the fix is to enhance the sorting
#       by finding the insertion point in the sorted array and to shift
#       righthand side using memmove()"
