    perf symbols: Remove perf_session usage in symbols layer · 9de89fe7
    Arnaldo Carvalho de Melo 提交于
    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.
