I sure hope this does not end up like EXPERIMENTAL although it essentially does duplicate the intent of EXPERIMENTAL. (In other words - drivers live there for ever in staging mode, we print warnings and generally nobody cares about the problem since the kernel is tainted.)
That aside please at least substitute the word CRAP with something better - like TAINT_NON_PRODUCTION or TAINT_UNRELIABLE or TAINT_WORK_IN_PROGRESS or TAINT_EXPERIMENTAL . Arguably TAINT_EXPERIMENTAL could also be used for known broken CONFIG_EXPERIMENTAL items. It might also be better to change the staging directory name to non-production or experimental - but that's just my preference.
Also, I suppose it would be useful for Production machines to have a kernel command line flag or something to say don't load staging modules - for instance to prevent against automatic loading on drivers from staging directory to support some oddball device etc.
Thinking more about it - could this whole thing not be achieved by setting per module experimental flag and refusing to insmod'ing experimental modules if -f was not specified. I believe force loading also taints the kernel? All drivers intended for staging can set that flag - this way we don't need another TAINT flag and there is no need for the directory name hack.
