From 25742aeb135c4a44e92fb347e037adaa145b9484 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Google)" Date: Wed, 20 Dec 2023 08:10:28 -0500 Subject: ring-buffer: Remove stale comment from ring_buffer_size() It's been 11 years since the ring_buffer_size() function was updated to use the nr_pages from the buffer->buffers[cpu] structure instead of using the buffer->nr_pages that no longer exists. The comment in the code is more of what a change log should have and is pretty much useless for development. It's saying how things worked back in 2012 that bares no purpose on today's code. Remove it.
