Subject: [PATCH AUTOSEL 4.19 20/22] virtio-blk: Fix memory leak among suspend/resume procedure
Date: Sat, 10 Jul 2021 19:51:41 -0400	[thread overview]
Message-ID: <20210710235143.3222129-20-sashal@kernel.org> (raw)
In-Reply-To: <20210710235143.3222129-1-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().
