CVE-2022-49914

CVE-2022-49914 involves the Linux kernel btrfs backref walk leak in resolve_indirect_refs(). When an error occurs, code previously freed the parents list with ulist_free(), but attached inode lists via the aux field were not freed, causing a leak. The fix replaces ulist_free() with free_leaf_list...
