From e4e676d74ac72ca20ea4b59f296a5cc332bc1a3e Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Wed, 14 Aug 2024 12:58:12 +0200 Subject: [PATCH] multiple-pipeline: reduce debug verbosity Dumping all tasks even on a dedicated test system, running Ubuntu generates too much output, which is difficult to find useful information in. Dump waiting tasks and locks help instead to identify kernel dead-locks.
