/*
* bpf_cgrp_storage_get
*
* Get a bpf_local_storage from the *cgroup*.
*
* Logically, it could be thought of as getting the value from
* a *map* with *cgroup* as the **key**. From this
* perspective, the usage is not much different from
* **bpf_map_lookup_elem**\ (*map*, **&**\ *cgroup*) except this
* helper enforces the key must be a cgroup struct and the map must also
* be a **BPF_MAP_TYPE_CGRP_STORAGE**.
*
* In reality, the local-storage value is embedded directly inside of the
* *cgroup* object itself, rather than being located in the
* **BPF_MAP_TYPE_CGRP_STORAGE** map. When the local-storage value is
* queried for some *map* on a *cgroup* object, the kernel will perform an
* O(n) iteration over all of the live local-storage values for that
* *cgroup* object until the local-storage value for the *map* is found.
*
* An optional *flags* (**BPF_LOCAL_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_LOCAL_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.
*
* Returns
* A bpf_local_storage pointer is returned on success.
*
* **NULL** if not found or there was an error in adding
* a new bpf_local_storage.
