  1. fix: directIO read size can exceed buffer size 

    Since the package uses a fixed-size memory pool for out messages,
it is important to tell fuse kernel module what the maximum read size is.
Otherwise, a large read will cause a panic.

Right now, max readahead size can only affect buffered read. The kernel
might still send a large directIO read in spite of the max readahead size.
We need to specify "max_read" option during mount.
