The following document may be helpful: "SBC-4 SPC-5 Atomic writes and
reads" (http://www.t10.org/cgi-bin/ac.pl?t=d&f=13-064r9.pdf). Please
note that the information about atomic writes in that document has been
superseded by the section in the SBC-4 document about atomic writes
(http://www.t10.org/cgi-bin/ac.pl?t=f&f=sbc4r07c.pdf).
Bart.
