Looks fine, except that the DIOCCACHESYNC ioctl is being invoked 
incorrectly.  The argument is actually an "int", not a "long".  
Non-zero tells the driver to issue the command even if it does not 
consider any blocks to be dirty (the sd driver keeps track of this so 
it can know if it needs to issue the command on close, etc.)
