I've tweaked your text a bit to make some details clearer (I hope):
readahead() initiates readahead on a file so that subsequent
reads from that file will, be satisfied from the cache, and not
block on disk I/O (assuming the readahead was initiated early

meantime flush pages from the cache).
Slight grammatical error there: there's an extra comma in "file will, be".
