13 | mm/page_alloc: fix tracepoint mm_page_alloc_zone_locked() | ||
14 | |||
15 | Currently, trace point mm_page_alloc_zone_locked() doesn't show correct | ||
16 | information. | ||
17 | |||
18 | First, when alloc_flag has ALLOC_HARDER/ALLOC_CMA, page can be allocated | ||
19 | from MIGRATE_HIGHATOMIC/MIGRATE_CMA. Nevertheless, tracepoint use | ||
20 | requested migration type not MIGRATE_HIGHATOMIC and MIGRATE_CMA. | ||
21 | |||
22 | Second, after commit 44042b4498728 ("mm/page_alloc: allow high-order pages | ||
23 | to be stored on the per-cpu lists") percpu-list can store high order | ||
24 | pages. But trace point determine whether it is a refiil of percpu-list by | ||
25 | comparing requested order and 0. | ||
26 | |||
27 | To handle these problems, make mm_page_alloc_zone_locked() only be called | ||
28 | by __rmqueue_smallest with correct migration type. With a new argument | ||
29 | called percpu_refill, it can show roughly whether it is a refill of | ||
30 | percpu-list. | ||
31 | |||
32 | Upstream-Status: Backport | ||
33 | |||
