I think that the concern is that the exact implementation is actually
already coded and relatively easy for us to do (i.e., send down unmap
commands at natural file system level units after a truncate/delete).
The irony is that the hard part is to try to approach that level of
exactness with the other techniques (coalescing unmaps, defrag, etc) :-)
I was using "exact" in the second sense... our battle about
matching exactly with an array where the thin unmap chunk is
greater than the natural file system level unit.
Saying in that case, extreme measures are not justified.
