+ * Search for a subvolume by given type (received uuid, root id, path), returns
+ * pointer to newly allocated struct subvol_info or NULL in case it's not found
+ * or there was another error. This ambiguity of error value is fixed by
+ * subvol_uuid_search2 that returns a negative errno in case of an error, of a
+ * valid pointer otherwise.
+ *
+ * This function will be deprecated in the future, please consider using v2 in
+ * new code unless you need to keep backward compatibility with older
+ * btrfs-progs.
