We're planning to make GFS/GNBD to work on top of TIPC in hope that will
give better performance over TCP. Since TIPC provides socket-like APIs,
our initial thinking was to just convert socket APIs in GFS/GNBD code to
TIPC socket-like APIs. Based on what you described, making GFS/GNBD to
work on top of ICS may be a better alternative.
Could you give me some pointers on how to make GFS/GNBD to work on ICS?
