+ mm_page_alloc_zone_locked() (v5.19)
+

+ commit 10e0f7530205799e7e971aba699a7cb3a47456de

+
+ 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.

+ workqueue: Fix type of cpu in trace event
+
+ The trace event "workqueue_queue_work" use unsigned int type for
+ req_cpu, cpu. This casue confusing cpu number like below log.
+
+ $ cat /sys/kernel/debug/tracing/trace
+ cat-317 [001] ...: workqueue_queue_work: ... req_cpu=8192 cpu=4294967295
+
+ So, change unsigned type to signed type in the trace event. After
+ applying this patch, cpu number will be printed as -1 instead of
+ 4294967295 as folllows.
+
+ $ cat /sys/kernel/debug/tracing/trace
+ cat-1338 [002] ...: workqueue_queue_work: ... req_cpu=8192 cpu=-1

+ net: skb: introduce kfree_skb_reason()
+
+ Introduce the interface kfree_skb_reason(), which is able to pass
+ the reason why the skb is dropped to 'kfree_skb' tracepoint.
+
+ Add the 'reason' field to 'trace_kfree_skb', therefor user can get
+ more detail information about abnormal skb with 'drop_monitor' or
+ eBPF.
+
+ All drop reasons are defined in the enum 'skb_drop_reason', and
+ they will be print as string in 'kfree_skb' tracepoint in format
+ of 'reason: XXX'.
+
+ ( Maybe the reasons should be defined in a uapi header file, so that
+ user space can use them? )
