* diskstats.h -- statistics for physical disk drives
*
* A tx_diskstats[] and tx_diskbusy[] entry exists for each physical disk
* in the TX system. MAX_DSK tx_diskstats[] and tx_diskbusy[] entries are
* valloc'ed at init time in module dskalloc() in file tsdev/dsk.c . The
* mapping from the RTE device handle to the tx_diskstats[] and
* tx_diskbusy[] array index is performed via the DSTAT_IX macro. The
* tx_diskstats[] and tx_diskbusy[] arrays are located via txinfo
* pointers.
