H A Dbpftool-iter.rst35 A bpf iterator combines a kernel iterating of
37 and a bpf program called for each kernel data object
41 The *pin* command creates a bpf iterator from *OBJ*,
47 Map element bpf iterator requires an additional parameter
48 *MAP* so bpf program can iterate over map elements for
49 that map. User can have a bpf program in kernel to run
53 User can then *cat PATH* to see the bpf iterator output.
