Subject: [PATCH 6.6 02/11] Revert "workqueue: Dont call cpumask_test_cpu() with -1 CPU in wq_update_node_max_active()"
Date: Wed, 3 Apr 2024 19:55:51 +0200 [thread overview]
Message-ID: <20240403175126.919810055@linuxfoundation.org> (raw)
In-Reply-To: <20240403175126.839589571@linuxfoundation.org>
6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
This reverts commit 7df62b8cca38aa452b508b477b16544cba615084 which is
commit 15930da42f8981dc42c19038042947b475b19f47 upstream.
The workqueue patches backported to 6.6.y caused some reported
regressions, so revert them for now.
