From 1c5eb4481e0151d579f738175497f998840f7bbc Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (VMware)" Date: Thu, 9 Jan 2020 18:53:48 -0500 Subject: tracing: Rename trace_buffer to array_buffer As we are working to remove the generic "ring_buffer" name that is used by both tracing and perf, the ring_buffer name for tracing will be renamed to trace_buffer, and perf's ring buffer will be renamed to perf_buffer. As there already exists a trace_buffer that is used by the trace_arrays, it needs to be first renamed to array_buffer.
