This patch sets the io_pages bdi hint based on the rsize mount option. Without this patch large buffered reads (request size > max readahead) are processed sequentially in chunks of the readahead size (i.e. read requests are sent out up to the readahead size, then the do_generic_file_read() function waits until the first page is received). With this patch read requests are sent out at once up to the size specified in the rsize mount option (default: 64 MB). Signed-off-by:
