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