[Xen-devel] oo_req, rd_req, wr_req... cant find any docs

[Shaun Reitan <mailinglists@xxxxxxxxxxxxxxxx>]

I cannot seam to find any documentation on 
/sys/devices/vbd-<domid>-<##>/statistics/ and am trying to figure out 
what these stats represent.  From the looks of it rd_req means read 
requests.  Are these read requests that have already been completed? or 
can they be requests that are waiting/queued?
What is oo_req, all i can find on it is some comments about them being 
mysterious.
Another doc I found talks about rd_bytes but i don't see that, i do see 
rd_sect which i assume is sectors.  So is this whats meant for measuring 
how much has been transferred (assuming 512 bytes per sector)?
