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 still need to add support for automatic detection of underlying
device's flushing capabilities but first I would like to know if you
agree with the general approach.
I'll be replying to this email with the new patches.
