[Lustre-devel] Question of transplanting Lustre to a non-x86 arch

[Light&ColoR]

Thx, Chris, it's really helpful to me. Right, I use Linux, and I saw the architecture-specific code exactly in some of these kernel patches.  Although I need servers and clients, I think there is not too much work to do.....^ ^
