ansible - ansible 中 flush_handlers 的替代方案

Question

我的 Ansible 剧本中有处理程序，我想立即触发这些通知。如何在不调用 meta_handler = flush_handler 的情况下实现这一点？ ?
这在 Ansible 2.5.6 中运行良好，但在此版本之后会显示一条警告:

[WARNING]: flush_handlers task does not support when conditional

任何帮助，将不胜感激。

这是一个 Unresolved 问题 meta: flush_handlers doesn't honor when clause #41313 .

引用我的comment :

Let me describe a valid scenario (below). "flush_hadlers" is needed after tasks abc.yml complete and before tasks def.yml start. But the file with the tasks xyz.yml is imported when OS is RH only. Here Ansible complains:

[WARNING]: flush_handlers task does not support when conditional

能够抑制警告会很好。

# cat xyz.yml
- include_tasks: abc.yml
- meta: flush_handlers
- include_tasks: def.yml

# cat playbook.yml
  ...
  tasks:
    - import_tasks: xyz.yml
      when: (ansible_os_family == "RedHat" )
