debian/patches: 19 patches to forward upstream
low
Among the 20 debian patches
available in version 1:128.4.3esr-1 of the package,
we noticed the following issues:
19 patches
where the metadata indicates that the patch has not yet been forwarded
upstream. You should either forward the patch upstream or update the
metadata to document its real status.
This package is part of the ongoing testing transition known as llvm-defaults-19.
Please avoid uploads unrelated to this transition, they would
likely delay it and require supplementary work from the release
managers. On the other hand, if your package has problems
preventing it to migrate to testing, please fix them
as soon as possible.
You can probably find supplementary information in the
debian-release
archives or in the corresponding
release.debian.org
bug.
