+    mkfs.gfs2: Tighten minimum journal size checks
+    
+    mkfs.gfs2 chooses the default journal size based on the block size and
+    the size of the target device, and when the device is small enough a
+    minimum journal size is enforced. If the block size is less than 4K and
+    the device is small enough a journal size can be chosen that is smaller
+    than the minimum and gfs2 will not mount it, as it has a hardcoded check
+    for >=8MB journals. To avoid that we can just clamp the journal size
+    back to 8MB in these cases. A validity check for the minimum has already
+    been done in default_journal_size().
+
