2022-04-08T22:54:37+00:00

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 The cache backend is using fscache_wait_for_objects() to wait all objects to be withdrawn.

docs: filesystems: caching/backend-api.rst: correct two relinquish APIs use

2022-04-08T22:54:37+00:00

1. cache backend is using fscache_relinquish_cache() rather than fscache_relinquish_cookie() to reset the cache cookie. 2. No fscache_cache_relinquish() helper currently, it should be fscache_relinquish_cache().
