To inform the vendor and to post a warning about the issue on lkml was the right thing to do. It is the wording of your post that obviously irked some people. > Martin's cleanup patch is good and I never claimed otherwise, I just > said the comment on the commit was a bad call (as there are users of > that interface).

The correct thing to say would have been "Nobody in the official kernel is using ptep_test_and_clear_dirty and ptep_clear_flush_dirty." nvidia will have to adapt their binary driver. This is not the first time it breaks and it won't be the last time. We do not really have a problem and we should all calm down and put that issue to rest. -- blue skies, Martin.
