A similar patch has been submitted about a month ago within our LRO patches. The LRO code won't be sent here since we are waiting for the core stack to implement a generic LRO. Please consider this single patch for 2.6.20. As explained previously, the complete driver code in our CVS also supports high-order allocations instead of single physical pages since it significantly increase the performance. But, since high-order allocations are generally considered a bad idea, we do not include the relevant code in the following patch for inclusion in Linux. Here, we simply pass order=0 to all page allocation routines. Thanks, Brice
