Subject: [PATCH] zsmalloc: don't test shrinker_enabled in zs_shrinker_count()
Date: Wed, 14 Oct 2015 10:57:59 +0900 [thread overview]
Message-ID: <1444787879-5428-1-git-send-email-sergey.senozhatsky@gmail.com> (raw)
We don't let user to disable shrinker in zsmalloc (once
it's been enabled), so no need to check ->shrinker_enabled
in zs_shrinker_count(), at the moment at least.
