Memcache \OC\Memcache\APCu not available for local cache when using Redis

[k1ngf15h3r]

Nit sure this is a bug but need to have this clear. I have switched to Redis for memcache.local and memcache.locking like you can see below. In Admin page under Logging I get thread subject "Memcache \OC\Memcache\APCu not available for local cache" as Info entry. Is this only while Redis is used instead of APcu?

my config.php

[...]
'memcache.local' => '\\OC\\Memcache\\Redis',
'memcache.locking' => '\\OC\\Memcache\\Redis',
'redis' => array(
    'host' => 'redis',
    'port' => 6379,
),
'filelocking.enabled' => true,
'filelocking.ttl' => 60*60,
[...]

Steps to reproduce

1. Enable Redis in config.php for memcache
2. look into logging

Expected behaviour

no message

Actual behaviour

info message that memcache apcu not available

Reviewing other instances, seems to be a problem in 12.0.0, my 12.0.2 instance is okay, closing issue and try to fix it with an update to 12.0.2
