Changes since -U1: - bugfix: fix page_lock_anon_vma() crash reported by Adam Heath and Lorenzo Allegrucci. - bugfix: fix selinux atomic-schedule warning messages, reported by Mark H Johnson. - bugfix: ip_tables atomic-schedule fix, fixes the messages reported by Daniel Walker and K.R. Foley. - bugfix: fix warnings/deadlocks in inet_create(), reported by Mark H Johnson. - bugfix: fixed a crash-in-shmfs-during-heavy-swapout bug - bugfix: enable preemption while doing mmdrop() in the scheduler - it may schedule. - debugging feature: when PREEMPT_TIMING is enabled then the code also keeps a trace/stack of preemption enabler EIPs. (if LATENCY_TRACE is enabled as well then the parent EIP is recorded as well.) Whenever a stack trace due to atomicity violations is printed, the preemption stack is printed as well. This makes it much easier to identify the place that did the illegal preemption-disabling. to create a -U2 tree from scratch the patching order is: http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.8.tar.bz2 + http://kernel.org/pub/linux/kernel/v2.6/testing/patch-2.6.9-rc4.bz2 + http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.9-rc4/2.6.9-rc4-mm1/2.6.9-rc4-mm1.bz2 + http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.9-rc4-mm1-U2 Ingo - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
