3.0-stable review patch. If anyone has any objections, please let me know.


From: Miklos Szeredi <mszeredi@xxxxxxx>

commit c9e67d483776d8d2a5f3f70491161b205930ffe1 upstream.

In some cases fuse_retrieve() would return a short byte count if offset was
non-zero. The data returned was correct, though.
