I suspect this would be similar to what Chris did to merge btrfs while
retaining the standalone history. Chris, any pointers on what worked
well and what if anything you would do differently? I.e. I'm looking
to use git filter-branch to rewrite ndctl history as if if had always
been in tools/ndctl in the kernel tree. I found this old thread
https://lkml.org/lkml/2008/10/30/523 and it seems to also recommend
using an older kernel as the branch base.
