72   different CPU between getting the per-cpu variable and doing the

110 If you are already in a preemption-safe context, you can use
131 the ``local_t`` variable as a counter of bytes written in a buffer: there should
132 be a ``smp_wmb()`` between the buffer write and the counter increment and also a
133 ``smp_rmb()`` between the counter read and the buffer read.
136 Here is a sample module which implements a basic per cpu counter using
139     /* test-local.c
156             /* Increment the counter from a non preemptible context */
185             /* initialize the timer that will increment the counter */
