avoid repeated useless scans for memory. This is also useful to established sufficiently large off node allocation chunks to relieve the local node. It may be beneficial to adjust that time period for some special situations. For example if memory use was exceeding node capacity one may want to give up for longer periods of time. If memory spikes intermittendly then one may want to shorten the time period to reduce the number of off node allocations. This patch allows just that....

This avoids a zone suddenly loosing all unused pagecache pages (we may after all access some of these again so they deserve another chance) but it still frees up large chunks of memory if a zone only contains unused pagecache pages.

But it's muddled: each hugepage found covers HPAGE_SIZE, not PAGE_SIZE. Once pages were already in cache, it would overshoot, wrap its hugepages count backwards, and so fail a harmless repeat mapping with -ENOMEM. Fixes the problem found by Don Dupuis.

Without the cast, gcc considers ptrdiff_t a 64 bit signed integer and ends up emitting code to use a full signed 128 bit divide on EM64T, which is substantially slower than a 32 bit unsigned divide. I noticed this when looking at the profile of a case where the slab balance is just on edge and thrashes back and forth freeing a block.

Off node pagefault tests showed an 18% drop in performance without this patch. - Increase the timeout to 30 seconds to reduce the overhead. - Move all code possible out of the off node hot path for zone reclaim (Sorry Andrew, the struct initialization had to be sacrificed). The read_page_state() bit us there. - Check first for the timeout before any other checks.
