Hopefully that=E2=80=99s just = a symptom of nicer weather and holiday season, but we can still pick up = some momentum :) I wanted to get your input on the MODULE_LICENSE tag, which I have found = to be a bit vexing in some instances. I am finding examples where there = is a clearly identifiable license in the file, for example ISC, and then = the MODULE_LICENSE tag is something like "Dual BSD/GPL=E2=80=9D. There = is absolutely no other reference to GPL whatsoever (or any BSD variant = for that matter). Based on my understanding of = https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/in= clude/linux/module.h#n172 = - the MODULE_LICENSE info was never meant to = be definitive license info, but seemingly more of an approximation. = I=E2=80=99m wondering if others have a different view? More specifically - where we have specific license match (like the = example above) - we can add the appropriate SPDX identifier, but if we = leave the MODULE_LICENSE info, I suspect that scanners will pick that up = and report a mix of licensing info (e.g., ISC, BSD, GPL, as in my above = example), which kind of brings us to the same place we are now. Should = we also remove the MODULE_LICENSE tag where it contradicts the actual = license info in terms of an exact license match (i.e., there is nothing = to match to GPL here, other than the MODULE_LICENSE tag, but there is an = exact match to a different license, ISC, in this case).
