You said you will send a new patch instead of replying here, and then now you are saying you will keep aking to this thread. I'm confused. [...] Ok, I think this discussion is going unnecessarily deep and only wasting our time at clarifying intention of past sentence. Meanwhile apparently you understood my major points. To repeat, please clarify what is the problem and user impacts, when and how it happens, and why the solution solves it. Let's restart. Could you please rewrite the commit log for this patch and send the draft as a reply to this? We can further discuss on the new draft if it has more things to improve. And once the discussion is finalized, you can post v4 of this patch with the updated commit message. Thanks, SJ
