But regressionss continue to be reported: https://lore.kernel.org/lkml/cb5b81bd-9882-e5dc-cd22-54bdbaaefbbc@leemhuis.info/ https://bugzilla.kernel.org/show_bug.cgi?id=215720 https://lkml.kernel.org/r/b685f3d0-da34-531d-1aa9-479accd3e21b@leemhuis.info This patch reverts the fix, so the original can also be reverted.
