Subject: [PATCH 2/3] bcache-tools: add is_zoned_device()
Date: Sat, 16 May 2020 22:09:39 +0800	[thread overview]
Message-ID: <20200516140940.101190-3-colyli@suse.de> (raw)
In-Reply-To: <20200516140940.101190-1-colyli@suse.de>

This is a wrapper of get_zone_size(), to check whether a device is
zoned device or not by checking its chunk_sectors.
