    [PATCH] completely disable cpu_exclusive sched domain · 212d6d22
    Paul Jackson authored
    At the suggestion of Nick Piggin and Dinakar, totally disable
    the facility to allow cpu_exclusive cpusets to define dynamic
    sched domains in Linux 2.6.13, in order to avoid problems
    first reported by John Hawkes (corrupt sched data structures
    and kernel oops).
    
    This has been built for ppc64, i386, ia64, x86_64, sparc, alpha.
    It has been built, booted and tested for cpuset functionality
    on an SN2 (ia64).
    
    Dinakar or Nick - could you verify that it for sure does avoid
    the problems Hawkes reported.  Hawkes is out of town, and I don't
    have the recipe to reproduce what he found.
