>Description:
ioctl(2) RAIDFRAME_GET_ACCTOTALS is unusable from userland

There is lack of RF_AccTotals_t definition in public headers.
>How-To-Repeat:
$ grep -r RF_AccTotals_t /usr/include/                                                                                                                                               
/usr/include/dev/raidframe/raidframeio.h:#define RAIDFRAME_GET_ACCTOTALS     _IOR ('r', 17, RF_AccTotals_t)     /* retrieve AccTotals

>Fix:
Either remove the functionality or export needed date to userland.
