What doesn't work?  Passing pinfo is straightforward, so that presumably
works, and there's something else, e.g. some call to "col_add_str()" or
"col_append_fstr()" or something such as that, that's not working.

If so, what are the calls you're making in the subdissectors?  They
should be something like

	if (check_col(pinfo->cinfo, COL_INFO)) {
		col_append_fstr(pinfo->cinfo, COL_INFO, ", Foo %s",
		    op_string);
	}

Note that "col_add_str()" and "col_add_fstr()" will *overwrite* what
"dissect_afs()" puts into the column, so, unless you *want* to trash the
operation name, etc., you need to use "col_append_str()" or
"col_append_fstr()", to *append* to what "dissect_afs()" put into the
column.
