From 348139384ba30eccd4ce4f01fcf575b08ce81b83 Mon Sep 17 00:00:00 2001 From: Ilpo Järvinen Date: Fri, 15 Dec 2023 17:04:50 +0200 Subject: selftests/resctrl: Change function comments to say < 0 on error MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A number function comments state the function return non-zero on failure but in reality they can only return 0 on success and < 0 on error. Update the comments to say < 0 on error to match the behavior. While at it, improve cat_val() comment to state that 0 means the test was run (either pass or fail).
