One way is to have an intermediary function:

   int lstat (const char *path, struct stat *statbuf)
   {
     char real_path[FILENAME_MAX];
     ...
     if (!__solve_dir_symlinks(path, real_path))
       return -1;
     ...
     if (try_fsext (&ret, real_path, statbuf))
       return ret;

     if (stat_assist (real_path, statbuf))
      ...

where try_fsext is this:

   static int try_fsext (int *ret, const char *path, struct stat *statbuf)
   {
     return __FSEXT_call_open_handlers (__FSEXT_stat, ret, &path);
   }
