Subject: [PATCH] pack-redundant: fix memory leak when open_pack_index() fails
Date: Sat, 21 Feb 2026 16:08:59 +0530	[thread overview]
Message-ID: <20260221103900.41740-1-sahityajb@gmail.com> (raw)

In add_pack(), we allocate l.remaining_objects with llist_init() before
calling open_pack_index(). If open_pack_index() fails we return NULL
without freeing the allocated list, leaking the memory.

Fix by calling llist_free(l.remaining_objects) on the error path before
returning.
