I think the customary lines for bug references and fixed commits are:

 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=102496
 Fixes: eceb671002 (mesa/st: Reduce the number of frontbuffer flush calls)

As those get picked up by the scripts for eg. stable management. You might want
to use those tags.

Cheers,
Kai
