Subject: [PATCH] md/raid5: simplify uninitialization of shrinker
Git-commit: 565e0450129647df5112bff3df3ffd02b0c08e32
Patch-mainline: v4.16-rc4
References: bsc#1093023
Don't use shrinker.nr_deferred to check whether shrinker was
initialized or not. Now this check was integrated into
unregister_shrinker(), so it is safe to call it against
unregistered shrinker.
