Subject: [PATCH v2 4/6] block: blk_root(): return non-const pointer
Date: Wed, 21 Jul 2021 17:04:22 +0300	[thread overview]
Message-ID: <20210721140424.163701-5-vsementsov@virtuozzo.com> (raw)
In-Reply-To: <20210721140424.163701-1-vsementsov@virtuozzo.com>

In the following patch we'll want to pass blk children to block-copy.
Const pointers are not enough. So, return non const pointer from
blk_root().
