This question need to be though.
The good thing about the current dedup log is that the code is already wr=
itten
and match very well the dedup usage.

Aside my personal interest of resuming the work on deduplication quickly =
I think
we should consider the overall cost of having a specialized log for dedup=
e.

Is the reviewing and maintainance of http://patchwork.ozlabs.org/patch/25=
2955/
a reasonable extra cost ?
