From 0ae446e4b91b5a713fb189cf7f23d1a303057fd9 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Tue, 15 Dec 2020 20:43:01 -0800 Subject: lib/test_free_pages.c: add basic progress indicators The test module to check that free_pages() does not leak memory does not provide any feedback whatsoever its state or progress, but may take some time on slow machines. Add the printing of messages upon starting each phase of the test, and upon completion.
