Hi, Keir.

I changed the location to outputs statistical information of virtual block 
device (VBD)
from the /proc file system to the sysfs.
The location is 'statstics' directory under each VBD directory,
for example, /sys/devices/xen-backend/vbd-x-xxxx/statistics.

The 'statistics' directory includes the following three statistical 
informations.
  oo_req
       is the number of Out of(?) requests.
  rd_req
       is the number of pended READ requests.
  wr_req
       is the number of pended WRITE requests.

These patches provide the function to output the information to sysfs.
It does not include the modifications of a xentop command and a libxenstat 
library
(these were included by the former patches).
I plans to release the patches of xentop and libxenstat as soon as possible. 


Thanks,
Satoshi UCHIDA.
