I have been running SNAPSHOT r3425-f28eef4 on BT Home Hub 5 for the last hour with airtime_flags untouched and it appears stable.

I am not sure whether https://git.lede-project.org/?p=source.git;a=commit;h=764cd09dd845864b0d45c6b1f914b81612a5dd28 is included but I have seen lots of updates on lantiq ath9k when I have done a git pull. 

How do I check whether a commit is included in my pull?
