Cover letter [PATCH,RFC 00/02] xprtrdma: Client Fast Memory Registration Support
This set of patches implements support for Fast Memory Registration in the NFS client. Fast Memory Registration is enabled by writing 6 to the rdma_memreg_strategy proc file as follows:
# echo 6 > /proc/sys/sunrpc/rdma_memreg_strategy
If Fast Memory Registration is not supported by the device, the memory registration strategy reverts to a global default that is supported by all RDMA adapters.
