[PATCH 25/28] mm, page_alloc: Inline pageblock lookup in page free fast paths

The function call overhead of get_pfnblock_flags_mask() is measurable in the page free paths. This patch uses an inlined version that is faster. Signed-off-by: Mel Gorman --- include/linux/mmzone.h | 7 -- mm/page_alloc.c| 188 ++--- mm/page_

To read pid/cid registers, the probed device need to be properly turned on.

However in some cases power domain (or clocks) might not be yet available. Retu

[PATCH 05/27] mm, vmscan: Have kswapd only scan based on the highest requested zone

kswapd checks all eligible zones to see if they need balancing even if it was woken for a lower zone. This made sense when we reclaimed on a per-zone basis because we wanted to shrink zones fairly so avoid age-inversion problems. Ideally this is completely unnecessary when reclaiming on a per-node

[PATCH 08/27] mm, vmscan: Simplify the logic deciding whether kswapd sleeps

kswapd goes through some complex steps trying to figure out if it should stay awake based on the classzone_idx and the requested order. It is unnecessarily complex and passes in an invalid classzone_idx to balance_pgdat(). What matters most of all is whether a larger order has been requsted and wh

[PATCH 04/27] mm, vmscan: Begin reclaiming pages on a per-node basis

This patch makes reclaim decisions on a per-node basis. A reclaimer knows what zone is required by the allocation request and skips pages from higher zones. In many cases this will be ok because it's a GFP_HIGHMEM request of some description. On 64-bit, ZONE_DMA32 requests will cause some problems

[PATCH 02/27] mm, vmscan: Move lru_lock to the node

Node-based reclaim requires node-based LRUs and locking. This is a preparation patch that just moves the lru_lock to the node so later patches are easier to review. It is a mechanical change but note this patch makes contention worse because the LRU lock is hotter and direct reclaim and kswapd can

[PATCH 06/27] mm, vmscan: Make kswapd reclaim in terms of nodes

Patch "mm: vmscan: Begin reclaiming pages on a per-node basis" started thinking of reclaim in terms of nodes but kswapd is still zone-centric. This patch gets rid of many of the node-based versus zone-based decisions. o A node is considered balanced when any eligible lower zone is balanced. This

[PATCH 24/27] mm, page_alloc: Remove fair zone allocation policy

The fair zone allocation policy interleaves allocation requests between zones to avoid an age inversion problem whereby new pages are reclaimed to balance a zone. Reclaim is now node-based so this should no longer be an issue and the fair zone allocation policy is not free. This patch removes it.
