version that should be applied. If there is any doubt, the maintainer
will reply and ask what should be done.
+Q: I made changes to only a few patches in a patch series should I resend only those changed?
+--------------------------------------------------------------------------------------------
+A: No, please resend the entire patch series and make sure you do number your
+patches such that it is clear this is the latest and greatest set of patches
+that can be applied.
+
+Q: I submitted multiple versions of a patch series and it looks like a version other than the last one has been accepted, what should I do?
+-------------------------------------------------------------------------------------------------------------------------------------------
+A: There is no revert possible, once it is pushed out, it stays like that.
+Please send incremental versions on top of what has been merged in order to fix
+the patches the way they would look like if your latest patch series was to be
+merged.
+
Q: How can I tell what patches are queued up for backporting to the various stable releases?
--------------------------------------------------------------------------------------------
A: Normally Greg Kroah-Hartman collects stable commits himself, but for
