The -commits list is just a convenience mainly for reviewers, but you
can also just look on the cgit web interface and find the commit very
easily if you know what to expect and when it was done etc. In this case
it took only 10 seconds for me to spot:
Likely a less time than it took to send the email asking for the sha1 :)
All the best!
