By default, FUSE runs in cached I/O mode[1]. That means some I/O
responses will be taken from the page cache instead of being handled by
the FUSE process. For files opened for reading that's not a problem as
all the requests are just passed through.
However, that is problematic for files opened for writing since those
requests need to be handled by the backend. It's particularly bad for a
file opened `O_RDWR` since `read` responses from the page cache are
likely to be wrong. Instruct FUSE to use `direct-io` for those files so
that the page cache is bypassed.
