Would it be possible to get those patches applied?

Simon has started doing some testing with the automatic I/O sync
barriers. It is still not working 100% properly, but it is apparently
not worse than it was. And clearly the current situation is not good,
and those patches make it slightly better.

Thanks,

Thomas
