While testing the second patch I ran into a pinned page leak in the
vhost_vdpa_pa_map() error path. The first patch fixes that and is
tagged for stable.
The second patch unpins each IOTLB mapping as a range with
unpin_user_page_range_dirty_lock(), which marks each folio dirty once
and drops its pins in one go, instead of a set_page_dirty_lock() and
unpin_user_page() per page. It removes the last use of
set_page_dirty_lock() in vhost.
