Subject: [ 41/46] fuse: fix retrieve length

From: Greg KH <gregkh@...uxfoundation.org>

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

------------------

From: Miklos Szeredi <mszeredi@...e.cz>

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.
