no worries, in this case it is probably harmless.

here it works.

we did everything, now we fsync and ioctl BLKFLSBUF
just because we are paranoid.
and it does not work, because the argp is 0x1000, instead of 0.
compare the both BLKFLSBUF ioctls.
aparently one may not leave off the explicit NULL,
even if the ioctl does not need/use any parameter at all.
please try this patch
