might be useful.
1. Slab allocation of small objects of unknown type
These events are similar in usage to the kmalloc-related events except that
it is likely easier to pin the event down to a specific cache. At the time
of writing, no information is available on what slab is being allocated from,
-but the call_site can usually be used to extrapolate that information
+but the call_site can usually be used to extrapolate that information.
3. Page allocation
==================
When the per-CPU list is too full, a number of pages are freed, each one
which triggers a mm_page_pcpu_drain event.
-The individual nature of the events are so that pages can be tracked
+The individual nature of the events is so that pages can be tracked
between allocation and freeing. A number of drain or refill pages that occur

+consecutively imply the zone->lock being taken once. Large amounts of per-CPU
refills and drains could imply an imbalance between CPUs where too much work
is being concentrated in one place. It could also indicate that the per-CPU
lists should be a larger size. Finally, large amounts of refills on one CPU
Large numbers of this event implies that memory is fragmenting and
high-order allocations will start failing at some time in the future. One

min_free_kbytes in increments of 3*pageblock_size*nr_online_nodes where
pageblock_size is usually the size of the default hugepage size.
