There is one update/fix to the (upstream still unused) cpu_clock() API. [ which API will replace all the current (and buggy) in-tree uses of sched_clock(). ] There are also two small facilities added: preempt-notifiers (which is disabled and not selectable by the user and hence a NOP) needed by future KVM and other virtualization work and they'd like to see this offered by the upstream kernel. There's also the new above_background_load() inline function (unused at the moment). The presence of these two facilities causes no change at all to the kernel image: text data bss dec hex filename 5573413 679332 3842048 10094793 9a08c9 vmlinux.before 5573413 679332 3842048 10094793 9a08c9 vmlinux.after so i thought this would be fine for a post-rc1 merge too. There's also two small cleanup patches, a documentation update, and a debugging enhancement/helper: i've merged Nick's long-pending sysctl-domain-tree debug patch that has been in -mm for 3 years meanwhile. (It depends on CONFIG_SCHED_DEBUG and has no effect on scheduling by default even if enabled.) passes allyesconfig, allnoconfig and distro build, boots and works fine on 32-bit and 64-bit x86 as well. (and is expected to work fine on every architecture) Ingo --------------------> Avi Kivity (1): sched: arch preempt notifier mechanism Con Kolivas (1): sched: add above_background_load() function Ingo Molnar (2): sched: increase SCHED_LOAD_SCALE_FUZZ sched: make cpu_clock() not use the rq clock Joachim Deguara (1): sched: update Documentation/sched-stats.txt Josh Triplett (1): sched: mark sysrq_sched_debug_show() static Nick Piggin (1): sched: debug feature - make the sched-domains tree runtime-tweakable Satoru Takeuchi (1): sched: remove unused rq->load_balance_class Documentation/sched-stats.txt | 195 ++++++++++++++++++++-------------------- include/linux/preempt.h | 44 +++++++++ include/linux/sched.h | 23 ++++ kernel/Kconfig.preempt | 3 kernel/sched.c | 204 ++++++++++++++++++++++++++++++++++++++++-- kernel/sched_debug.c | 2 6 files changed, 365 insertions(+), 106 deletions(-)
