Kuan-Wei Chiu a1c78bcc70 tracing: Fix cmp_entries_dup() to respect sort() comparison rules ... commit e63fbd5f6810ed756bbb8a1549c7d4132968baa9 upstream. The cmp_entries_dup() function used as the comparator for sort() violated the symmetry and transitivity properties required by the sorting algorithm. Specifically, it returned 1 whenever memcmp() was non-zero, which broke the following expectations: * Symmetry: If x < y, then y > x. * Transitivity: If x < y and y < z, then x < z. These violations could lead to incorrect sorting and failure to correctly identify duplicate elements. Fix the issue by directly returning the result of memcmp(), which adheres to the required comparison properties.
