25 Heavy activity for these events may indicate that a specific cache is
37   kmem_cache_alloc_node	call_site=%lx ptr=%p bytes_req=%zu bytes_alloc=%zu gfp_flags=%s node=%d
40 These events are similar in usage to the kmalloc-related events except that
41 it is likely easier to pin the event down to a specific cache. At the time

60 amounts of activity imply high activity on the zone->lock. Taking this lock
61 impairs performance by disabling interrupts, dirtying cache lines between
72 contention on the zone->lru_lock.

81 In front of the page allocator is a per-cpu page allocator. It exists only
82 for order-0 pages, reduces contention on the zone->lock and reduces the

86 the zone->lock will be taken once and the per-CPU list refilled. The event
90 When the per-CPU list is too full, a number of pages are freed, each one
95 consecutively imply the zone->lock being taken once. Large amounts of per-CPU
97 is being concentrated in one place. It could also indicate that the per-CPU
98 lists should be a larger size. Finally, large amounts of refills on one CPU
99 and drains on another could be a factor in causing large amounts of cache

117 means of reducing the occurrence of this event is to increase the size of
119 pageblock_size is usually the size of the default hugepage size.
