Christoph, I reworked my previous fsync() patches so that what was a mount option to trigger a storage device writeback cache flush becomes a sysfs knob.

I'll be replying to this email with the new patches. - Fernando -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
