 * HP-UX versions below 10.20:
 *
 *    The pool_id_t type does not seem to be defined in the header  files
 *    distributed by HP.  However, <sys/fs/vx_hpux.h> requires  it when
 *    _KERNEL is defined.  So we fake the pool_id_t definition.
 *
 *    <sys/fs/vx_hpux.h> also requires sv_sema_t.  It's defined in
 *    <sys/sem_alpha.h> when _KERNEL is defined, but some other header file has
 *    already included <sys/sem_alpha.h> with _KERNEL undefined.  So we fake the
 *    sv_sema_t definition.
 *
 * HP-UX version 10.20 and above:
 *
 *    The pool_id_t type is used by other header files for other purposes.
 *    Redefine it for VXFS.  Delete some other conflicting definitions.
 *    Don't #define _KERNEL.  Include a different set of VXFS header files.
