37 When this key type is used, then all attach types of the particular cgroup and
39 ``struct bpf_cgroup_storage_key``, then programs of different attach types
133 multiple attach types, and each attach creates a fresh zeroed storage. The
145 does not already contain an entry for the cgroup and attach type pair, or else
146 the old storage is reused for the new attachment. If the map is attach type
147 shared, then attach type is simply ignored during comparison. Storage is freed
158 In all versions, userspace may use the attach parameters of cgroup and
159 attach type pair in ``struct bpf_cgroup_storage_key`` as the key to the BPF map
