This patchset includes the per-cpu-pages stuff which Martin and I
have been working on. This is designed to:
- increase the probability of the page allocator returning a page
which is cache-warm on the calling CPU
- amortise zone->lock contention via work batching.
- provide the basis for a page reservation API, so we can guarantee
that some troublesome inside-spinlock allocations will succeed.
Mainly pte_chains and radix_tree_nodes (haven't implemented this yet).
I must say that based on a small amount of performance testing the
benefits of the cache warmness thing are disappointing. Maybe 1% if
you squint. Martin, could you please do a before-and-after on the
NUMAQ's, double check that it is actually doing the right thing?
And Anton, could you please test this, make sure that it fixes the
rmqueue() and __free_pages_ok() lock contention as effectively as
the old per-cpu-pages patch did? Thanks.
There is a reiserfs compilation problem at present.
Rick has a modified version of iostat. Please use that for extracting the
SARD info. Also the version at http://linux.inet.hr/ is reasonably uptodate.
New versions of procps are at http://surriel.com/procps/ - the version
from cygnus CVS works for me.
