 .Pp
 The allocation and management of the reference counter is handled by the
 subsystem.
-The developer can check whether the reference count for the
-external storage of a given
-.Vt mbuf
-is greater than 1 with the
-.Dv MEXT_IS_REF
-macro.
-Similarly, the developer can directly add and remove references,
-if absolutely necessary, with the use of the
-.Dv MEXT_ADD_REF
-and
-.Dv MEXT_REM_REF
-macros.
 .Pp
 The system also supplies a default type of external storage buffer called an
 .Vt mbuf cluster .
