Actually, the parted BLKFLSBUF tickles a bug that was in ext3 2.2 for
a while (hit that on an internal server).  Didn't we discuss removing
this call entirely?  Basically, if a device is in-use in the kernel
calling BLKFLSBUF is not sufficient to force all buffers to disk (it
will refuse to flush busy buffers), and we won't be able to change a
partition that is in-use anyways.

A patch for parted-1.6 is below.

Cheers, Andreas
