From 382d7efc14a38baa8b8b91115891ef00fe5a5076 Mon Sep 17 00:00:00 2001 From: Andrea Righi Date: Mon, 6 Jan 2025 08:20:34 +0100 Subject: [PATCH] sched_ext: Include remaining task time slice in error state dump Report the remaining time slice when dumping task information during an error exit. This information can be useful for tracking incorrect or excessively long time slices in schedulers that implement dynamic time slice logic.
