Compared to my pull eysterday: A one character fix in get_buffer patch spotted by Peter Xu Compared to Juan's pull: a) Hopefully fixed non-Linux builds (Local build test on mingw64 works Note: the zero-copy capability is now defined on non-Linux systems) b) Added Hyman's series - it had been on queue for a while (sorry for the delay) In this today migration PULL request: - Dainiel Berrangé - qemufileops cleanup - Leonardo Bras - cleanups for zero copy - Juan Quintela - RDMA cleanups - Hyman Huang - per-vcpu dirty ring work Signed-off-by: Dr. David Alan Gilbert ---------------------------------------------------------------- Daniel P.
