[PATCH for-next v8 00/10] RDMA/rxe: Implement memory windows

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This series of patches implement memory windows for the rdma_rxe
driver. This is a shorter reimplementation of an earlier patch set.
They apply to and depend on the current for-next linux rdma tree.
