mountstats: Fix nfsstat command to handle RPC iostats version >= 1.1
Later kernels with RPC iostats version >= 1.1 have an additional errors count for each op. Lengthen the array of values created inside DeviceData and then in __parse_rpc_line just zero this value out for prior kernels where this count is not present. The count is not used for nfsstat, but this keeps DeviceData consistent with the new count as well as proper functioning of accumulate_iostats. Before this patch, nfsstat will backtrace on a kernel with RPC iostats version >= 1.1 due to the fixed array inside DeviceData. This patch fixes this backtrace and also allows nfsstat to work with these new kernels. Signed-off-by: Dave Wysochanski <dwysocha@redhat.com> Signed-off-by: Steve Dickson <steved@redhat.com>
