Although it is not specified in the RFCs, the concept that the NFSv4 server should reply to an RPC request within a reasonable time is accepted practice within the NFSv4 community. Without this patch, the NFSv4.2 server attempts to reply to a Copy operation within 1 second by limiting the copy to vfs.nfs.maxcopyrange bytes (default 10Mbytes). This is crude at best, given the large variation in I/O subsystem performance. This patch uses the COPY_FILE_RANGE_TIMEO1SEC flag added by commit c5128c48 to limit the reply time for a Copy operation to approximately 1 second. MFC after: 2 weeks
