    ring-buffer: disable all cpu buffers when one finds a problem · 077c5407
    Steven Rostedt authored
    Currently the way RB_WARN_ON works, is to disable either the current
    CPU buffer or all CPU buffers, depending on whether a ring_buffer or
    ring_buffer_per_cpu struct was passed into the macro.
    Most users of the RB_WARN_ON pass in the CPU buffer, so only the one
    CPU buffer gets disabled but the rest are still active. This may
    confuse users even though a warning is sent to the console.
    This patch changes the macro to disable the entire buffer even if
    the CPU buffer is passed in.
