Support for O_DIRECT in fuse is a work still in progress (patches are
under review/resubmit in fuse-devel and linux-fsdevel). You can use
liboindirect (https://github.com/avati/liboindirect) as a temporary
workaround in case you cannot modify your application to not use
O_DIRECT and you cannot wait till the native support is ready.
