Subject: [PATCH AUTOSEL 4.14 19/21] virtio-blk: Fix memory leak among suspend/resume procedure
Date: Sat, 10 Jul 2021 19:52:10 -0400	[thread overview]
Message-ID: <20210710235212.3222375-19-sashal@kernel.org> (raw)
In-Reply-To: <20210710235212.3222375-1-sashal@kernel.org>

From: Xie Yongji <xieyongji@bytedance.com>

[ Upstream commit b71ba22e7c6c6b279c66f53ee7818709774efa1f ]

The vblk->vqs should be freed before we call init_vqs()
in virtblk_restore().
