+ * Common interface definitions for making balloon pages movable by compaction.
+ *
+ * Despite being perfectly possible to perform ballooned pages migration, they
+ * make a special corner case to compaction scans because balloon pages are not
+ * enlisted at any LRU list like the other pages we do compact / migrate.
+ *
+ * As the page isolation scanning step a compaction thread does is a lockless
+ * procedure (from a page standpoint), it might bring some racy situations while
+ * performing balloon page compaction. In order to sort out these racy scenarios
+ * and safely perform balloon's page compaction and migration we must, always,
+ * ensure following these three simple rules:
+ *
+ * i. when updating a balloon's page ->mapping element, strictly do it under
+ * the following lock order, independently of the far superior
+ * locking scheme (lru_lock, balloon_lock):
+ * +-page_lock(page);
+ * +--spin_lock_irq(&b_dev_info->pages_lock);
+ * ... page->mapping updates here ...
+ *
+ * ii. before isolating or dequeueing a balloon page from the balloon device
+ * pages list, the page reference counter must be raised by one and the
+ * extra refcount must be dropped when the page is enqueued back into
+ * the balloon device page list, thus a balloon page keeps its reference
+ * counter raised only while it is under our special handling;
+ *
+ * iii. after the lockless scan step have selected a potential balloon page for
+ * isolation, re-test the page->mapping flags and the page ref counter
+ * under the proper page lock, to ensure isolating a valid balloon page
+ * (not yet isolated, nor under release procedure)
+ *
+ * The functions provided by this interface are placed to help on coping with
+ * the aforementioned balloon page corner case, as well as to ensure the simple
+ * set of exposed rules are satisfied while we are dealing with balloon pages
+ * compaction / migration.
