Files created with dd either directly on the s3f3 mounted volume or copied to 
it are 0k in size


When I attempt to create some dummy test data with either the fallocate or dd 
command on the s3fs mounted volume, the resulting file is 0k in size no matter 
what size I try to make it. 

If I create the file on a local partition using dd of fallocate, the file is 
created with the correct size. However, when I attempt to copy it to the s3fs 
mounted volume, the file size is 0k.

I am able to other local files from the system to the s3fs mounted volume and 
the size is reported correctly.
