[PATCH,RFC 00/02] xprtrdma: Client Fast Memory Registration Support

[Tom Tucker <tom@opengridcomputing.com>]

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.

This patches are also available here:
