Hi Anna- Here is the first set of NFS/RDMA client patches for v4.15. These close a window where async RPCs that never receive a Reply will terminate but let the memory invalidation happen later. I don't think there was much of an exposure here. Hard async RPCs typically just hang anyway, they can't be interrupted. Please consider these patches for v4.15. --- Chuck Lever (3): xprtrdma: Don't defer fencing an async RPC's chunks xprtrdma: Use ro_unmap_sync in xprt_rdma_send_request xprtrdma: Remove ro_unmap_safe net/sunrpc/xprtrdma/fmr_ops.c | 19 ------------------- net/sunrpc/xprtrdma/frwr_ops.c | 19 ------------------- net/sunrpc/xprtrdma/transport.c | 5 +++-- net/sunrpc/xprtrdma/xprt_rdma.h | 2 -- 4 files changed, 3 insertions(+), 42 deletions(-) -- Chuck Lever -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
