Why isn't it inherited from the parent dataset ?
The logbias property which effects ZIL behaviour is inherited.
It can see having it inherited being useful for setting on a parent
dataset that contains a large number of ZVOLs being used for COMSTAR
or filesystems for NFS where all of them need the same sync behaviour.
We've flip-flopped on whether it should be inherited. It's currently
coded as inherited, and I know Robert believes it should stay that way.
Anyway, it was generally felt by the zfs group that sync=disabled
was sufficiently dangerous to require explicit setting on each dataset.
I would be ok with it being inherited.
