Not So Direct I/O (8 minute read)
Even when using O_DIRECT with 4 KB-aligned reads and writes, read(2) can return fewer than 4096 bytes if the file's logical end falls before the end of its final physical sector. This occurs because direct I/O bypasses the page cache but still depends on the filesystem's logical-to-physical mapping, so EOF can occur mid-sector—meaning applications must handle short reads and not assume a full block will always be returned.
