From 9de89fe7c577847877ae00ea1aa6315559b10243 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 3 Feb 2010 16:52:00 -0200 Subject: perf symbols: Remove perf_session usage in symbols layer MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit I noticed while writing the first test in 'perf regtest' that to just test the symbol handling routines one needs to create a perf session, that is a layer centered on a perf.data file, events, etc, so I untied these layers. This reduces the complexity for the users as the number of parameters to most of the symbols and session APIs now was reduced while not adding more state to all the map instances by only having data that is needed to split the kernel (kallsyms and ELF symtab sections) maps and do vmlinux relocation on the main kernel map.
