5 BPF_MAP_TYPE_CGRP_STORAGE  title
8 The ``BPF_MAP_TYPE_CGRP_STORAGE`` map type represents a local fix-sized
15 ``BPF_MAP_TYPE_CGRP_STORAGE`` map type.
37 A BPF program example with BPF_MAP_TYPE_CGRP_STORAGE::
44             __uint(type, BPF_MAP_TYPE_CGRP_STORAGE);
78 Difference Between BPF_MAP_TYPE_CGRP_STORAGE and BPF_MAP_TYPE_CGROUP_STORAGE
83 ``BPF_MAP_TYPE_CGRP_STORAGE`` map should be used instead. The following
84 illusates the main difference between ``BPF_MAP_TYPE_CGRP_STORAGE`` and
87 (1). ``BPF_MAP_TYPE_CGRP_STORAGE`` can be used by all program types while
91 (2). ``BPF_MAP_TYPE_CGRP_STORAGE`` supports local storage for more than one
97      ``BPF_MAP_TYPE_CGRP_STORAGE`` allocates local storage at runtime so
103 (4). ``BPF_MAP_TYPE_CGRP_STORAGE`` supports deleting local storage by a BPF program
107 So overall, ``BPF_MAP_TYPE_CGRP_STORAGE`` supports all ``BPF_MAP_TYPE_CGROUP_STORAGE_DEPRECATED``
108 functionality and beyond. It is recommended to use ``BPF_MAP_TYPE_CGRP_STORAGE``
