DTRACE: Argument to nfsv4:::op-remove-start ?

I want to track "rmdir" executed over NFS by a client, to determine which client is doing a particular rmdir.

I believe this will show on the server with the dtrace probe

nfsv4:::op-remove-start

args[0]->ci_remote     will give me the client

args[1]->noi_curpath   will give me the parent directory

and I believe args[2]->target should be the actual name of the file (a directory in this case) that is being removed.

More precisely args[2] is of type

struct REMOVE4args

{

   component4 target;

};

typedef utf8str_cs component4

However, I don't know how to deal with a utf8str_cs in a dtrace script. I know the directory name is of course ascii.
