NAME
iob_prefetch - prefetch data for I/O batch
SYNTAX
#include <iob.h>
void iob_prefetch(io_batch* b,uint64 n);
DESCRIPTION
iob_prefetch makes sure the next n bytes are in memory.
This is useful when serving large files over the network concurrently.
Prefetching the data can then reduce hard disk head movement and
enhance throughput.
