From b9bae2c841b73eac6bfed510bc24a3051754ff51 Mon Sep 17 00:00:00 2001 From: Kan Liang Date: Tue, 6 Mar 2018 10:36:07 -0500 Subject: perf mmap: Simplify perf_mmap__read_init() It isn't necessary to pass the 'start', 'end' and 'overwrite' arguments to perf_mmap__read_init(). The data is stored in the struct perf_mmap. Discard the parameters.
