That is correct, as this commit (13cf01744608 ("iommu/vt-d: Make use of iova deferred flushing")) did originally show up in 4.14: $ git describe --contains 13cf01744608 v4.14-rc1~72^2^14~3 But, that commit ended up in a stable release, the 4.9.104 release. Oh. nope, crap, my fault, my scripts pick up the fact that we refer to commit 13cf01744608 in a 4.9 commit, but only the fact that it is _not_ in the 4.9.y tree. Sorry, my fault, scripts are only so good at times. > I'll send v4.19 -stable patch shortly.. > And will prepare v4.14 patch (as we don't have v4.14 release, I need to > actually port it). Thanks for doing the backport, and sorry for the 4.9.y noise, you were right here, my scripts were wrong. greg k-h
