Code review comment for ~liushuyu-011/ubuntu/+source/libzstd:ubuntu/devel

Changes such as this do NOT need to go via Debian first. This is in the sponsorship queue to be uploaded to Ubuntu, and we should not be redirecting contributors to land such changes in Debian first, particularly when they concern architectural differences between Debian and Ubuntu (autopkgtests on i386 pass in Debian, and not in Ubuntu because i386 is a partial arch for us).

Our policy is to forward changes to Debian and try to reduce the delta from Debian where possible, not to block improving Ubuntu on getting agreement from Debian first.
