Patches

diff-nf-nat-targets-init-20080228-3

Patch from Dmitry Mishin <dim@parallels.com>

If ip_conntrack_disable_ve0 option is set, than it is impossible to use nat targets (DNAT, SNAT) inside Containers even if nat table is permitted for them and respective modules are loaded. This patch fixes above issue.

Fixed and tested by Konstantin Khlebnikov <khlebnikov@openvz.org>.

diff-sched-load-balance-09012008

Patch from Alexandr Andreev <aandreev@openvz.org>

[SCHEDULER] fix load_balance() behavior, when it's invoked on a busy PCPU.

Note: looks like it works, but not sure about any kind of performance any more. Now we can trust performance results for VE's with --cpus 1

diff-fix-cpufreq-ondemand-20080220

Patch from Konstantin Khlebnikov <khlebnikov@openvz.org>

CPU frequency switch may be incorrect on some hardware.

Ondemand use queue_delayed_work_on call and suppose that it works correctly. Farsched schedule kernel threads on random cpu and timer event may called not on supposed cpu.

This leads to CPU frequency is set almost randomly.

Bug #98868.
