Subject: [PATCH 01/10] cgroup: make cftype->private a unsigned long
Date: Sun, 12 Jul 2015 14:00:34 -0400 [thread overview]
Message-ID: <1436724043-12986-2-git-send-email-tj@kernel.org> (raw)
In-Reply-To: <1436724043-12986-1-git-send-email-tj@kernel.org>
It's pretty unusual to have an int as a private data field and it
makes it impossible to carray a pointer value through it. Let's make
it an unsigned long. AFAICS, this shouldn't break anything.
