**bpftool struct_ops { show | list }** [*STRUCT_OPS_MAP*]
	  Show brief information about the struct_ops in the system.
	  If *STRUCT_OPS_MAP* is specified, it shows information only
	  for the given struct_ops.  Otherwise, it lists all struct_ops
	  currently existing in the system.

	  Output will start with struct_ops map ID, followed by its map
	  name and its struct_ops's kernel type.

**bpftool struct_ops dump** [*STRUCT_OPS_MAP*]
	  Dump details information about the struct_ops in the system.
	  If *STRUCT_OPS_MAP* is specified, it dumps information only
	  for the given struct_ops.  Otherwise, it dumps all struct_ops
	  currently existing in the system.

**bpftool struct_ops register** *OBJ* [*LINK_DIR*]
	  Register bpf struct_ops from *OBJ*.  All struct_ops under
	  the ELF section ".struct_ops" and ".struct_ops.link" will
	  be registered to its kernel subsystem.  For each
	  struct_ops in the ".struct_ops.link" section, a link
	  will be created.  You can give *LINK_DIR* to provide a
	  directory path where these links will be pinned with the
	  same name as their corresponding map name.

**bpftool struct_ops unregister**  *STRUCT_OPS_MAP*
	  Unregister the *STRUCT_OPS_MAP* from the kernel subsystem.

**bpftool struct_ops help**
	  Print short help message.
