From 3effc2f165a842d640873e29d4c5cc1650143aef Mon Sep 17 00:00:00 2001 From: Kan Liang Date: Thu, 18 Jan 2018 13:26:25 -0800 Subject: perf mmap: Discard legacy interface for mmap read Discards perf_mmap__read_backward() and perf_mmap__read_catchup(). No tools use them. There are tools still use perf_mmap__read_forward(). Keep it, but add comments to point to the new interface for future use.
