That's very strong statement. It may be true, but I would like to see
reference to either kernel discussion or kernel source code.

GRUB also performs fsync() which should synchronize filesystem and block
device state. What you describe sounds more like broken filsystem which fails
to properly implement fsync(). Now, *that* was known and I won't mind adding
workaround for this but I want to understand what we are trying to fix.
