Subject: [PATCH 4/8] docs: filesystems: caching/backend-api.rst: fix an object
withdrawn API
From: Yue Hu <huyue2@...lpad.com>
There's no fscache_are_objects_withdrawn() helper at all to test if
cookie withdrawal is completed currently. The cache backend is using
fscache_wait_for_objects() to wait all objects to be withdrawn.
