Chao, Got it~
Eric, Actually, I wanted to detour the internal readahead mechanism using page_cache_ra_unbounded() to generate cluster size aligned read requests. But, page_cache_async_readahead() or page_cache_sync_readahead() can be also good enough, since those can compensate for the misaligned reads reading more pages in advance.
