Subject: [PATCH] cgroup: explicitly init the early_init field
Date: Tue, 22 Apr 2014 13:27:29 +0800	[thread overview]
Message-ID: <1398144449-9325-1-git-send-email-nasa4836@gmail.com> (raw)

For a cgroup subsystem who should init early, then it should carefully
take care of the implementation of css_alloc, because it will be called
before mm_init() setup the world.

Luckily we don't, and we better explicitly assign the early_init field
to 0, for document reason.
