		* void bpf_sk_storage_get(struct bpf_map map, struct bpf_sock sk, void value, u64 flags)
		* Description
		* Get a bpf-local-storage from a sk.
		*
		* Logically, it could be thought of getting the value from
		* a map with sk as the key. From this
		* perspective, the usage is not much different from
		* bpf_map_lookup_elem(map, &sk) except this
		* helper enforces the key must be a bpf_fullsock()
		* and the map must be a BPF_MAP_TYPE_SK_STORAGE also.
		*
		* Underneath, the value is stored locally at sk instead of
		* the map. The map is used as the bpf-local-storage type.
		* The bpf-local-storage type (i.e. the map) is searched
		* against all bpf-local-storages residing at sk.
		*
		* An optional flags (BPF_SK_STORAGE_GET_F_CREATE) can be
		* used such that a new bpf-local-storage will be
		* created if one does not exist. value can be used
		* together with BPF_SK_STORAGE_GET_F_CREATE to specify
		* the initial value of a bpf-local-storage. If value is
		* NULL, the new bpf-local-storage will be zero initialized.
		* Return
		* A bpf-local-storage pointer is returned on success.

		* -ENOENT if the bpf-local-storage cannot be found.
