From: Ran Xiaokai <[email protected]> Memblock pages (including reserved memory) should have their allocation tags initialized to CODETAG_EMPTY via clear_page_tag_ref() before being released to the page allocator. When kho restores pages through kho_restore_page(), missing this call causes mismatched allocation/deallocation tracking and warning message: alloc_tag was not set.
Add missing clear_page_tag_ref() annotation in kho_restore_page() to fix this.
