    workqueue: implement "workqueue.debug_force_rr_cpu" debug feature · f303fccb
    Tejun Heo authored
    Workqueue used to guarantee local execution for work items queued
    without explicit target CPU.  The guarantee is gone now which can
    break some usages in subtle ways.  To flush out those cases, this
    patch implements a debug feature which forces round-robin CPU
    selection for all such work items.
    The debug feature defaults to off and can be enabled with a kernel
    parameter.  The default can be flipped with a debug config option.
