[Maria-developers] Lack of linkage from MariaDB JIRA to commits

All, I have noticed that the MariaDB JIRA tickets are rarely linked to any specific commit which purportedly fixes them. Is there any standard at the moment for what should be done (and then it isn't followed) or is there no standard (and perhaps it should be made)? I would really like a consistent way to get to view the commits into various branches related to each MDEV issue, in a consistent way. Regards, Jeremy
