Name:g_buffer_record_enable_cpu - enable writes to the buffer*@buffer: The ring buffer to enable writes*@cpu: The CPU to enable.* Note, multiple disables will need the same number of enables* to truly enable the writing (much like preempt_disable).
Proto:void ring_buffer_record_enable_cpu(struct ring_buffer *buffer, int cpu)
Type:void
