5 | * The pattern is dynamically allocated, but that doesn't mean there | |
6 | * are not limits. The network protocol has a limit of | |
7 | * FIO_SERVER_MAX_CMD_MB and potentially two patterns must fit in there. | |
8 | * There's also a need to verify the incoming data from the network and | |
9 | * this provides a sensible check. | |
10 | * | |
11 | * 128MiB is an arbitrary limit that meets these criteria. The patterns | |
12 | * tend to be truncated at the IO size anyway and IO sizes that large | |
13 | * aren't terribly practical. | |
