6.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> This reverts commit 43f0cec175f92c7a01e43d5d6f276262670a97ed which is commit 31c89007285d365aa36f71d8fb0701581c770a27 upstream. The workqueue patches backported to 6.8.y caused some reported regressions, so revert them for now.
