[Bug 1558447] Re: vivid/linux: total ADT test failures


That sounds about right. Confusingly the email refers to the latter
patch saying it might be fixed by that. Unfortunately it looks like the
revert has been part of the fix and we already had both in vivid when
undoing the revert was not only no longer needed but probably even fatal
without the misapply.

While looking through the current history of that file, I noticed yet
another tweak around that area. So maybe, while reverting the wrong
revert of the revert, it might be worth looking at
