Common usage of the call ( see the ureadahead, sreadahead packages ),
inspection of blktrace data while using these packages, discussion on linux-mm,
inspection of the kernel sources.  The call *can* block, for instance, if it
must read ext2/3 indirect blocks to map the data blocks so their reads can be
queued, but the whole point of the call is to *avoid* blocking.
