Hi Neil,

please apply this patch! It is correct, now.

It applies to 3.2.y, 3.4.y, 3.7.y and latest 3.8-rc5. All these versions
are affected by this bug.

3.0.y and 2.6.34.y are also affected. Please also find the patches for
these versions attached. I've tested them. They work.

The strange thing is that 2.6.32.y is immune against this bug. So it
must be a regression. The patch restores the same behavior as present in
2.6.32: fsync receives success.

I've tested against the following versions: 3.8-rc5, 3.7.5, 3.4.28,
3.2.37, 3.0.61, 2.6.34.14 and 2.6.32.60.

Cheers,
Sebastian

Thanks!
I've added "Cc: stable@vger.kernel.org" and will forward it to Linus shortly.
