H A Dmap_of_maps.rst14 an outer map contains instances of a single type of inner map, for example
17 When creating an outer map, an inner map instance is used to initialize the
18 metadata that the outer map holds about its inner maps. This inner map has a
19 separate lifetime from the outer map and can be deleted after the outer map has
22 The outer map supports element lookup, update and delete from user space using
23 the syscall API. A BPF program is only allowed to do element lookup in the outer
30 - A BPF program cannot update or delete outer map entries.
65 program. Note that the outer array can only be modified from user space using
88 examples of declarative initialisation of outer maps.
93 This snippet shows how to create an array based outer map:
