33DESCRIPTION
34===========
35	**bpftool struct_ops { show | list }** [*STRUCT_OPS_MAP*]
36		  Show brief information about the struct_ops in the system.
37		  If *STRUCT_OPS_MAP* is specified, it shows information only
38		  for the given struct_ops.  Otherwise, it lists all struct_ops
39		  currently existing in the system.
40
41		  Output will start with struct_ops map ID, followed by its map
42		  name and its struct_ops's kernel type.
43
44	**bpftool struct_ops dump** [*STRUCT_OPS_MAP*]
45		  Dump details information about the struct_ops in the system.
46		  If *STRUCT_OPS_MAP* is specified, it dumps information only
47		  for the given struct_ops.  Otherwise, it dumps all struct_ops
48		  currently existing in the system.
49
50	**bpftool struct_ops register** *OBJ*
51		  Register bpf struct_ops from *OBJ*.  All struct_ops under
52		  the ELF section ".struct_ops" will be registered to
53		  its kernel subsystem.
54
55	**bpftool struct_ops unregister**  *STRUCT_OPS_MAP*
56		  Unregister the *STRUCT_OPS_MAP* from the kernel subsystem.
57
58	**bpftool struct_ops help**
59		  Print short help message.
