+Subject: [ANNOUNCE] xfsprogs: $reason
+
+Hi folks,
+
+The xfsprogs $branch branch in repository at:
+
+       git://git.kernel.org/pub/scm/fs/xfs/xfsprogs-dev.git
+
+has just been updated.
+
+Patches often get missed, so if your outstanding patches are properly reviewed
+on the list and not included in this update, please let me know.
+
+The for-next branch has also been updated to match the state of master.
+
+The new head of the $branch branch is commit:
+
+$(git log --oneline --format="%H" -1 $branch)
+
+New commits:
+
+$(git shortlog --format="[%h] %s" $LAST_HEAD..$branch)
+
+Code Diffstat:
+
+$(git diff --stat --summary -C -M $LAST_HEAD..$branch)
+EOF
+       fi
