perfMemory_bsd.cpp get_user_name_slow misses check ?

[Baesken, Matthias]

Hello,  I noticed that  perfMemory_bsd.cpp function

static char* get_user_name_slow(int vmid, TRAPS)

misses  the

    // Since we don't create the backing store files in directories
    // pointed to by symbolic links, we also don't follow them when
    // looking for the files. We check for a symbolic link after the
    // call to opendir in order to eliminate a small window where the
    // symlink can be exploited.
    //
    if (!is_directory_secure(usrdir_name)) {
      FREE_C_HEAP_ARRAY(char, usrdir_name);
      os::closedir(subdirp);
      continue;
    }


Check that  aix/linux/solaris    have .
Should this be added ?
