If anyone has any objections, please let me know. ------------------ From: Jinghao Jia [ Upstream commit 0ee352fe0d28015cab161b04d202fa3231c0ba3b ] The variable name num_progs causes confusion because that variable really controls the number of rounds the test should be executed. Rename num_progs into nr_tests for the sake of clarity.
