This patch breaks t5310 with the leak sanitizer enabled due to the leaking `struct strbuf line`. It needs the following diff on top:

diff --git a/t/helper/test-name-hash.c b/t/helper/test-name-hash.c
index 15fb8f853c..e4ecd159b7 100644
--- a/t/helper/test-name-hash.c
+++ b/t/helper/test-name-hash.c
@@ -19,5 +19,6 @@ int cmd__name_hash(int argc UNUSED, const char **argv UNUSED)
 		printf("%10"PRIu32"\t%10"PRIu32"\t%s\n", name_hash, full_hash, line.buf);
 	}
 
+	strbuf_release(&line);
 	return 0;
 }

I also plan to eventually have a deeper look at your patch series, but
didn't yet find the time to do so until now :(
