I thought this could be done with the new defrag api. I thought it had a
way to allocate a new donor file in a specific location so you could then
migrate the target file to those specific donor blocks.
I'm not aware of that ability in the defrag api.
There are ohsm patches to do things along those lines, but they haven't
been updated since 2.6.30 days as far as I know.
It seems this ability would be vital to e4defrag. Without it, it would end up being no better than filesystem agnostic defragmenters like shake. I'm almost certain there was some discussion in this direction a few years ago when e4defrag started being talked about, was it really not implemented?
