For the next Media Summit, I'd like to discuss some criteria in order to avoid drivers to stay at staging from longer than needed. We have drivers at staging that aren't touched since 2014 (except for trivial and cleanup changes or due to changes at kABI). It sounds really doubtful that such drivers will get any care anytime soon. The way I see from some developers is that they rush to get stuff under staging, but, once the code is there, they relax and pretend that their drivers are already at the Linux Kernel and are first class citizens. I suspect that part of such behavior is due to some sort of pressure from the vendors that are sponsoring their work, but, once things enter at staging, they stop their sponsorship to fix the problems there. Staging is not supposed to work like that: once the driver gets merged there, developers and their sponsors should actually be committing to do whatever required to get the driver done to be part of the Linux Kernel's full body, and not to stay forever on a sort of Kernel's refugee camp. If, for whatever reason this doesn't happen, we should be dropping those drivers after a while. So, I'd like to discuss a set of criteria we'll be adopting in order to decide when it is time to send unloved staging code to /dev/null.
