Subject: [PATCH v3 5/5] dm-writecache: output seq_count within status
Date: Thu, 31 Jan 2019 10:29:55 +0800	[thread overview]
Message-ID: <20190131022955.9920-6-yehs2007@zoho.com> (raw)
In-Reply-To: <20190131022955.9920-1-yehs2007-ytc+IHgoah0@public.gmane.org>

From: Huaisheng Ye <yehs1-6jq1YtArVR3QT0dZR+AlfA@public.gmane.org>

seq_count is important for flush operations, output it within status
for debugging and analyzing code behavior.
