Convert the anonymous struct within struct stage_data to use struct object_id. The following Coccinelle semantic patch was used to implement this, followed by the transformations in object_id.cocci:

@@
struct stage_data o;
expression E1;
@@
- o.stages[E1].sha
+ o.stages[E1].oid.hash
@@
struct stage_data *p;
expression E1;
@@
- p->stages[E1].sha
+ p->stages[E1].oid.hash
