Re: [Qemu-devel] [PATCH 0/3] RDMA error handling

[Michael R. Hines]

Reviewed-by: Michael R. Hines <address@hidden>

(By the way, I no longer work for IBM and no longer have direct access to RDMA 
hardware. If someone is willing to let me login to something that does in the 
future, I don't mind debugging things. I just don't have any hardware of my own 
anymore to debug, and the last time I tried to use software RDMA it was an 
unpleasurable experience.)
