37DESCRIPTION
38===========
39bpftool struct_ops { show | list } [*STRUCT_OPS_MAP*]
40    Show brief information about the struct_ops in the system. If
41    *STRUCT_OPS_MAP* is specified, it shows information only for the given
42    struct_ops.  Otherwise, it lists all struct_ops currently existing in the
43    system.
44
45    Output will start with struct_ops map ID, followed by its map name and its
46    struct_ops's kernel type.
47
48bpftool struct_ops dump [*STRUCT_OPS_MAP*]
49    Dump details information about the struct_ops in the system. If
50    *STRUCT_OPS_MAP* is specified, it dumps information only for the given
51    struct_ops.  Otherwise, it dumps all struct_ops currently existing in the
52    system.
53
54bpftool struct_ops register *OBJ* [*LINK_DIR*]
55    Register bpf struct_ops from *OBJ*.  All struct_ops under the ELF section
56    ".struct_ops" and ".struct_ops.link" will be registered to its kernel
57    subsystem.  For each struct_ops in the ".struct_ops.link" section, a link
58    will be created.  You can give *LINK_DIR* to provide a directory path where
59    these links will be pinned with the same name as their corresponding map
60    name.
61
62bpftool struct_ops unregister  *STRUCT_OPS_MAP*
63    Unregister the *STRUCT_OPS_MAP* from the kernel subsystem.
64
65bpftool struct_ops help
66    Print short help message.
