Also, The "V2 update" portion should be split into the part that you want in the changelog, without the '-' bullet points (in this case, the explanation for monontonic time), and the purely informational part that makes sense for the review but not for the git history (what changes were done against previous versions of the patch), which should go below the '---' line under the Signed-off-by chain, so it gets removed when imported to git. If Felipe decides to do these changes himself when he applies the patch, that's fine, otherwise please send the patch again as 'V3' tomorrow.
