Subject: [RFC PATCH bpf-next 7/9] cgroup: Add cgroup_put() in !CONFIG_CGROUPS case
Date: Tue, 10 May 2022 00:18:05 +0000	[thread overview]
Message-ID: <20220510001807.4132027-8-yosryahmed@google.com> (raw)
In-Reply-To: <20220510001807.4132027-1-yosryahmed@google.com>

From: Hao Luo <haoluo@google.com>

There is already a cgroup_get_from_id() in the !CONFIG_CGROUPS case,
let's have a matching cgroup_put() in !CONFIG_CGROUPS too.
