Hi Greg / Thomas and all involved here. First, apologies for necro-bumping this thread, but I'm working a backport of this patch to kernel 4.15 (Ubuntu) and then I noticed we have it on stable, but only in 4.19+. Since the fixes tag presents an old commit (since ~3.19), I'm curious if we have a special reason to not have it on long-term stables, like 4.9 or 4.14. It's a subtle portion of arch code, so I'm afraid I didn't see something that prevents its backport for previous versions. Thanks in advance, Guilherme
