It includes more driver fixes and improvements from Thomas Gleixner. Changes since -U8.1: - USB semaphore->completion conversion from Thomas Gleixner - netconsole fixes from Michal Schmidt - fbcon fixes - added counted semaphores, this is now used by firewire, XFS and ACPI. This could fix the firewire breakage - but testing would be welcome. - PREEMPT_ACTIVE irqs-enabled critical path removal. - fixed irqs-off raw spinlock primitives on UP: they enabled irqs before enabling preemption, creating a window for an interrupt to slip in and increase the critical path. - made the deadlock detector not crash the current process - it will just hang. This produces far nicer log output while still not endangering stability. Also, fixed a bug in the detector that happens if the trace buffer overflows. - made the atomic-counter-underflow detector non-fatal as well, for the same reasons. to create a -U9 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/realtime-preempt/realtime-preempt-2.6.9-rc4-mm1-U9 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/
