I would very much like to get rid of unused ancient wireless drivers but the problem is that it's next to impossible to know if someone still uses a driver, or if the driver is even working. For example, few months back I suggested removing one driver which I thought to be completely unused (forgot already the name of the driver) and to my big surprise there was still a user, and he reported it working with a recent kernel release.
So I don't know what to do. Should we try adding a warning like below? :)
"This ancient driver will be removed from the kernel in 2022, but if it still works send report to <...@...> to avoid the removal."
How do other subsystems handle ancient drivers?
