Description Chris Lalancette 2008-07-17 16:06:27 UTC 
Description of problem:
Customers often ask for the ability to attach greater than 16 devices to their
running PV domains.  RHEL 5.3 is adding the dom0 bits to do this, however, there
are some minor changes to the blkfront driver necessary to fully enable this.
