    perf symbols: Do lazy symtab loading for the kernel & modules too · c338aee8
    Arnaldo Carvalho de Melo 提交于
    Just like we do with the other DSOs. This also simplifies the
    kernel_maps setup process, now all that the tools need to do is
    to call kernel_maps__init and the maps for the modules and
    kernel will be created, then, later, when
    kernel_maps__find_symbol() is used, it will also call
    maps__find_symbol that already checks if the symtab was loaded,
    loading it if needed.
    
    Now if one does 'perf top --hide_kernel_symbols' we won't pay
    the price of loading the (many) symbols in /proc/kallsyms or
    vmlinux.
