I agree that some of the methods Tux3 uses to implement data integrity, sync
and friends may be worth lifting up to core, or better, to a library,
but we will
all be better served if such methods are given time to mature first. After all,
that basically describes the entire evolution of the VFS: new concepts start
in a filesystem, prove themselves useful, then may be lifted up to be shared.

It is important to get the order right: prove first, then lift.
