    Fix some issues with QEMUFile · 871d2f07
    aliguori authored
    This patch allows QEMUFile's read and write operations to return 
    negative error codes.  This is necessary to detect things like closed 
    streams during live migration.
    
    It also removes unused code for QEMUFileFD write path.  Finally, it 
    makes sure to avoid attempting to flush an output buffer if the file
    is only being used for input.  This was spotted by Uri Lublin.
