Chuck Lever ba69cd122e xprtrdma: Remove support for FMR memory registration ... FMR is not supported on most recent RDMA devices. It is also less secure than FRWR because an FMR memory registration can expose adjacent bytes to remote reading or writing. As discussed during the RDMA BoF at LPC 2018, it is time to remove support for FMR in the NFS/RDMA client stack. Note that NFS/RDMA server-side uses either local memory registration or FRWR. FMR is not used. There are a few Infiniband/RoCE devices in the kernel tree that do not appear to support MEM_MGT_EXTENSIONS (FRWR), and therefore will not support client-side NFS/RDMA after this patch. These are: - mthca - qib - hns (RoCE) Users of these devices can use NFS/TCP on IPoIB instead.
