perf symbols: Encapsulate dsos list head into struct dsos
This is a precursor patch to enable long name searching of DSOs using a rbtree. In this patch, a new dsos structure is created which contains only a list head structure for the moment. The new dsos structure is used, in turn, in the machine structure for the user_dsos and kernel_dsos fields. Only the following 3 dsos functions are modified to accept the new dsos structure parameter instead of list_head: - dsos__add() - dsos__find() - __dsos__findnew() Signed-off-by: Waiman Long <Waiman.Long@hp.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Don Zickus <dzickus@redhat.com> Cc: Douglas Hatch <doug.hatch@hp.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Scott J Norton <scott.norton@hp.com> Link: http://lkml.kernel.org/r/1412021249-19201-2-git-send-email-Waiman.Long@hp.com [ Move struct dsos to dso.h to reduce the dso methods depends on machine.h ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
