Description
Similar to LU-2424 patch http://review.whamcloud.com/4940, the OST_BUFSIZE should be increased to allow for multiple requests to be handled in a single buffer along with a corresponding reduction in OST_NBUFS. This should only be done for the OST_IO_PORTAL and not the other small request portals.
Otherwise, if we want to increase the PTLRPC_MAX_BRW_SIZE again, the old OST_BUFSIZE will not be large enough and we have an immediate protocol compatibility problem again.
