      perf session env: Rename exit method · 4c7de49a
      Arnaldo Carvalho de Melo 提交于
      The semantic associated in tools/perf/ with foo__delete(instance) is to
      release all resources referenced by 'instance' members and then release
      the memory for 'instance' itself.
      
      The perf_session_env__delete() function isn't doing this, it just does
      the first part, but the space used by 'instance' itself isn't freed, as
      it is embedded in a larger structure, that will be freed at other stage.
      
      For these cases we se foo__exit(), i.e. the usage is:
      
       void foo__delete(foo)
       {
               if (foo) {
                       foo__exit(foo);
                       free(foo);
               }
       }
      
      But when we have something like:
      
       struct bar {
               struct foo foo;
               . . .
       }
      
      Then we can't really call foo__delete(&bar.foo), we must have this
      instead:
      
       void bar__exit(bar)
       {
               foo__exit(&bar.foo);
               /* free other bar-> resources */
       }
      
       void bar__delete(bar)
       {
               if (bar) {
      		bar__exit(bar);
                      free(bar);
               }
       }
      
      So just rename perf_session_env__delete() to perf_session_env__exit().
