No objection, but as noted in previous discussions about it I think we
should have some clarity about what it means for contributors. I.e. that
when they're contributing to reftable/ it's BSD license, but for the
rest of the codebase it's GPLv2.
I've just submitted a series to address that more generally:
https://lore.kernel.org/git/cover-0.5-00000000000-20211002T091212Z-avarab@gmail.com/
I think with that clarification of what these in-tree subdirectory
"COPYING" files mean the only thing left is for the "RFC" label to be
dropped here.
From what I as not-a-lawyer think I know about how licenses work the
concept that we can have BSD licensed content in-tree that can be
extracted and legally used by anyone outside of it seems rather dubious.
I.e. if I author a cross-tree where "reftable/" uses some updated API,
isn't the result a derived work and now GPLv2 and not "cleanly" BSD
licensed? But that's a separate question, and ultimately a worry for any
out-of-tree users. So I don't really care. I also believe that we've had
that situation before with (I think) libgit2 taking snapshots of our
"xdiff", so maybe it's already deemed to be a complete non-issue.
All I'd like is for contributors to git.git not to be confused, which I
think with my series above won't be the case.
