As usual it is been tested on high end hardware kindly provided by www.osdlab.org. ftp://ftp.us.kernel.org/pub/linux/kernel/people/andrea/kernels/v2.4/2.4.14pre3aa2/ ftp://ftp.us.kernel.org/pub/linux/kernel/people/andrea/kernels/v2.4/2.4.14pre3aa2.bz2 Only in 2.4.14pre3aa1: 00_rcu-poll-1 Only in 2.4.14pre3aa2: 00_rcu-poll-2 Don't waste an additional cacheline, move the quiescent sequence number in the schedule_data so rcu become zerocost in terms of cpu cache and memory bandwith in the fast path. Only in 2.4.14pre3aa1: 10_numa-sched-12 Only in 2.4.14pre3aa2: 10_numa-sched-13 rediffed due rcu-poll changes. Only in 2.4.14pre3aa1: 10_vm-5 Only in 2.4.14pre3aa2: 10_vm-6 Merged max_mapped*10 logic from Linus, still not adding anon pages from the lru, so we can see the difference, I can readd the anon pages to the lru anytime as soon as it's clear what's better.
