this series improves the use_mm / unuse_mm interface by better
documenting the assumptions, and my taking the set_fs manipulations
spread over the callers into the core API.

improve use_mm / unuse_mm v2
Hi all,
this series improves the use_mm / unuse_mm interface by better
documenting the assumptions, and my taking the set_fs manipulations
spread over the callers into the core API.
Changes since v1:
- drop a few patches
- fix a comment typo
- cover the newly merged use_mm/unuse_mm caller in vfio
