    Exclamation How to disable software interrupts?

    On Intel x86 Kernel,
    local_bh_disable() is not effective for disabling software interrupts,
    when CONFIG_PREEMPT_HARDIRQS is enabled.

    From the include/linux/bottom_half.h
    +# define local_bh_disable() do { } while (0)

    Let us know any functions other than local_bh_disable that can disable software interrupts.
