[PATCH 1/5 v1] mm: add a new parameter `node` to `get/add/inc/dec_mm_counter`

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add a new parameter `node` to mm_counter for counting per process
per node rss.

Since pages can be migrated between nodes, `remove_migration_pte`
also needs to call `add_mm_counter`.

Notice that the `MM_SWAPENTS` doesn't exist on any node. So when
add_mm_counter is used to modify rss_stat.count[MM_SWAPENTS], its
`node` field should be `NUMA_NO_NODE`.

And there is no need to modify `resident_page_types`, because
`MM_NO_TYPE` is not used in `check_mm`.
