A Dbpftool-iter.rst31 A bpf iterator combines a kernel iterating of
33 and a bpf program called for each kernel data object
37 The *pin* command creates a bpf iterator from *OBJ*,
43 Map element bpf iterator requires an additional parameter
44 *MAP* so bpf program can iterate over map elements for
45 that map. User can have a bpf program in kernel to run
49 User can then *cat PATH* to see the bpf iterator output.
