From 5d3d5b9645b53691b2eee7607cf995bcfae46dd0 Mon Sep 17 00:00:00 2001 From: Yue Hu Date: Thu, 7 Apr 2022 19:02:39 +0800 Subject: [PATCH] docs: filesystems: caching/backend-api.rst: fix an object withdrawn API There's no fscache_are_objects_withdrawn() helper at all to test if cookie withdrawal is completed currently. The cache backend is using fscache_wait_for_objects() to wait all objects to be withdrawn.
