While decoding filelayout getdeviceinfo received, print out the information about the location of data servers (IPs). Generic getdeviceinfo tracepoints prints the MDS's ip for the dstaddr. In this patch, separate the MDS's address from the DS's addresses. Signed-off-by: Olga Kornievskaia <kolga@netapp.com> Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
