Sorry, I mixed this up with fsync. sys_sync is not working, just flushing the
buffer on umount.
When I brought in the timed flush, I tried to use kupdated
(superblock->s_dirty) and had a bunch of unwanted flush's during consecutive
writes, because setting sb->s_dirty is asynchronous to kupdated interval.
That's why I used the 2 seconds timer.
I will think about it again.
