[PATCH] fuse: add DESTROY operation
Add a DESTROY operation for block device based filesystems. With the help of
this operation, such a filesystem can flush dirty data to the device
synchronously before the umount returns.
This is needed in situations where the filesystem is assumed to be clean
immediately after unmount (e.g. ejecting removable media).
