Are we talking about the same patch here? https://lkml.org/lkml/2013/12/12/174 Which depends on yours only to revert your part. I plan to repost it but that still doesn't mean it will get merged because Johannes still has some argumnets against. I would like to start the discussion again because now we are so deep in circles that it is hard to come up with a reasonable outcome. It is still hard to e.g. agree on an actual fix for a real problem https://lkml.org/lkml/2013/12/12/129. While notification might be an issue as well it is more of a corner case than a regular one. So let's try to move on, agree on the "oom vs. PF_EXITING) first and lay out discussion for the notification in a new threa.
