Subject: [PATCH 09/15] bcache: recal cached_dev_sectors on detach
Date: Mon, 8 Oct 2018 20:41:15 +0800 [thread overview]
Message-ID: <20181008124121.20192-10-colyli@suse.de> (raw)
In-Reply-To: <20181008124121.20192-1-colyli@suse.de>
From: Shenghui Wang <shhuiw@foxmail.com>
Recal cached_dev_sectors on cached_dev detached, as recal done on
cached_dev attached.
Update the cached_dev_sectors before bcache_device_detach called
as bcache_device_detach will set bcache_device->c to NULL.
