b2c9e2fbba3253 Zi Yan 2022-05-12 285 * @boundary_pfn: pageblock-aligned pfn that a page might cross

b2c9e2fbba3253 Zi Yan 2022-05-12 288 * @isolate_before: isolate the pageblock before the boundary_pfn

b2c9e2fbba3253 Zi Yan 2022-05-12 290 * Free and in-use pages can be as big as MAX_ORDER-1 and contain more than one
b2c9e2fbba3253 Zi Yan 2022-05-12 291 * pageblock. When not all pageblocks within a page are isolated at the same
b2c9e2fbba3253 Zi Yan 2022-05-12 292 * time, free page accounting can go wrong. For example, in the case of
b2c9e2fbba3253 Zi Yan 2022-05-12 293 * MAX_ORDER-1 = pageblock_order + 1, a MAX_ORDER-1 page has two pagelbocks.

b2c9e2fbba3253 Zi Yan 2022-05-12 296 * When either pageblock is isolated, if it is a free page, the page is not
b2c9e2fbba3253 Zi Yan 2022-05-12 297 * split into separate migratetype lists, which is supposed to; if it is an
b2c9e2fbba3253 Zi Yan 2022-05-12 298 * in-use page and freed later, __free_one_page() does not split the free page
b2c9e2fbba3253 Zi Yan 2022-05-12 299 * either. The function handles this by splitting the free page or migrating
