6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Greg Kroah-Hartman gregkh@linuxfoundation.org
This reverts commit 43a181f8f41aca27e7454cf44a6dfbccc8b14e92 which is commit 31c89007285d365aa36f71d8fb0701581c770a27 upstream.
The workqueue patches backported to 6.6.y caused some reported regressions, so revert them for now.
