I don't remember a single case where somebody complained so hard
about unexport of a symbol that it was reinstated.
Instead there are plenty of 'unexport foo' in every kernel release.
Like commit 4bb218a65a43 ("fs: unexport buffer_check_dirty_writeback").
Surely they break some oot mods, so what? Complaining doesn't help.
