The direct I/O code is mapping the read request to the file system block. If the file size was not on a block boundary, the result would show the the read reading past EOF. This was only happening for the AIO case. The non-AIO case truncates the result to match file size (in direct_io_worker). This patch does the same thing for the AIO case, it truncates the result to match the file size if the read reads past EOF. When I/O completes the result can be truncated to match the file size without using i_size_read(), thus the aio result now matches the number of bytes read to the end of file.
