iob_prefetch − prefetch data for I/O batch
#include <libowfat/iob.h>
void iob_prefetch(io_batch* b,uint64 n);
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.
