Subject: [PATCH 10/15] blk-cgroup: remove pointless CONFIG_BLOCK ifdefs
Date: Wed, 20 Apr 2022 06:27:18 +0200 [thread overview]
Message-ID: <20220420042723.1010598-11-hch@lst.de> (raw)
In-Reply-To: <20220420042723.1010598-1-hch@lst.de>
No need to make BLK_CGROUP stubs conditional on CONFIG_BLOCK as they
can't be used without that.
