Open/create files that are opened with O_WRONLY with O_RDWR instead. When the writeback cache for FUSE is enabled, the kernel may have to generate read requests to fetch up-to-date pages for use in the cache (in case of partial writes). This means that when we receive a request to open or create a file with O_WRONLY, we need to open the underlying file with O_RDWR.
