Hi all, In the man page for man 2 readahead, it reads "readahead() blocks until the specified data has been read" (http://www.kernel.org/doc/man-pages/online/pages/man2/readahead.2.html), however obviously readahead() doesn't work like this, as it's not a synchronous IO submitter. Is the man-page out-of-dated?
