Hi folks,

This patch series aim to fix up or optimize some code about vfio
dirty log tracking.

patch 1: Optimize dirty log when unwind pin pages.
patch 2-3: Optimize promoting pinned_page_dirty_scope.
patch 4: Fix up dirty log missing when promote pinned_page_dirty_scope.
patch 5-7: Drop superfluous parameter "pgsize" of some functions.

Wish they improves the robustness of vfio dirty log tracking.

Thanks,
Keqian
