Is cool - I was wondering if you had the same funny NUMA zone layout. You
do not.
So there's some new non-terminating condition in there. It's definitely
the case that we're still failing to throttle kswapd as we should be doing,
but I left it as-is due to lack of reported problems (hah) and because the
fix does cause less reclaim via kswapd and more reclaim via direct reclaim.
Still. The relevant patches, in order, are at
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.9-rc4/2.6.9-rc4-mm1/broken-out:
vmscan-total_scanned-fix.patch
revert-vm-no-wild-kswapd.patch
balance_pgdat-cleanup.patch
no-wild-kswapd-2.patch
no-wild-kswapd-kswapd-continue.patch
I expect the first one will fix this up. Can you confirm?
