I just realized this series is missing documentation updates.  So I just
posted[1] RFC v2 of this series with two documentation update patches and
trivial commit messages wordsmithing.  Note that other parts are same to RFC
v1, including the damos_commit() bug and damos_migrate_dest name.

Please pick the version to your v3 of interleave patch series if possible.
