From b6a46f7263bd8ba0e545d79bd034c412f32b5875 Mon Sep 17 00:00:00 2001 From: Aaron Tomlin Date: Tue, 8 Aug 2023 13:03:29 +0100 Subject: [PATCH] workqueue: Rename rescuer kworker Each CPU-specific and unbound kworker kthread conforms to a particular naming scheme. However, this does not extend to the rescuer kworker. At present, a rescuer kworker is simply named according to its workqueue's name. This can be cryptic. This patch modifies a rescuer to follow the kworker naming scheme. The "R" is indicative of a rescuer and after "-" is its workqueue's name e.g. "kworker/R-ext4-rsv-conver". tj: Use "R" instead of "r" as the prefix to make it more distinctive and consistent with how highpri pools are marked.
