In the parallel universe where I spent most time everyone now need to learn how to make their things to work out-of-tree. And there is not much of business case trying to fix and improve core parts of linux. The turn around have increased a lot and there is no edge doing it. > We also need to recognize that it's expectable that some vendors are > not willing to engage on supporting a driver for a decade if they > expect their device to last 5 years only, and maybe we should make > some rules clear about mainlining drivers and what to expect for > users (in which case the end of support would be clear and nobody > would be surprised if the driver is removed at the end of its > maintenance, barring a switch to a community maintainer).
