Bugzilla Bug 217098: corruption of xen image if stored on XFS partition

apparently using xfs as backing store for xen guest block devices, using the blktap driver, is busted.

Ring any bells? I need to read up on what blktap does (apparently large parts in userspace, O_DIRECT + aio....)

Thanks,

-Eric
