-Subject: [PATCH 1/3] fix: mm/page_alloc: fix tracepoint
- mm_page_alloc_zone_locked() (v5.19)

-    mm/page_alloc: fix tracepoint mm_page_alloc_zone_locked()
-
-    Currently, trace point mm_page_alloc_zone_locked() doesn't show correct
-    information.
-
-    First, when alloc_flag has ALLOC_HARDER/ALLOC_CMA, page can be allocated
-    from MIGRATE_HIGHATOMIC/MIGRATE_CMA.  Nevertheless, tracepoint use
-    requested migration type not MIGRATE_HIGHATOMIC and MIGRATE_CMA.
-
-    Second, after commit 44042b4498728 ("mm/page_alloc: allow high-order pages
-    to be stored on the per-cpu lists") percpu-list can store high order
-    pages.  But trace point determine whether it is a refiil of percpu-list by
-    comparing requested order and 0.
-
-    To handle these problems, make mm_page_alloc_zone_locked() only be called
-    by __rmqueue_smallest with correct migration type.  With a new argument
-    called percpu_refill, it can show roughly whether it is a refill of
-    percpu-list.
