Subject: [PATCH 1/6] bfq-iosched: relocate bfqg_*rwstat*() helpers
Date: Thu,  7 Nov 2019 11:17:59 -0800	[thread overview]
Message-ID: <20191107191804.3735303-2-tj@kernel.org> (raw)
In-Reply-To: <20191107191804.3735303-1-tj@kernel.org>

Collect them right under #ifdef CONFIG_BFQ_CGROUP_DEBUG.  The next
patch will use them from !DEBUG path and this makes it easy to move
them out of the ifdef block.

This is pure code reorganization.
