    perf symbols: Rename kthreads to kmaps, using another abstraction for it · 9958e1f0
    Arnaldo Carvalho de Melo 提交于
    Using a struct thread instance just to hold the kernel space maps
    (vmlinux + modules) is overkill and confuses people trying to
    understand the perf symbols abstractions.
    
    The kernel maps are really present in all threads, i.e. the kernel
    is a library, not a separate thread.
    
    So introduce the 'map_groups' abstraction and use it for the kernel
    maps, now in the kmaps global variable.
    
    It, in turn, will move, together with the threads list to the
    perf_file abstraction, so that we can support multiple perf_file
    instances, needed by perf diff.
