Subject: [PATCH v2 05/13] btrfs-progs: Fix Wimplicit-fallthrough warning
Date: Wed, 5 Dec 2018 14:40:10 +0800 [thread overview]
Message-ID: <20181205064018.27755-6-wqu@suse.com> (raw)
In-Reply-To: <20181205064018.27755-1-wqu@suse.com>
Although most fallthrough case is pretty obvious, we still need to teach
the dumb compiler that it's an explicit fallthrough.
Also reformat the code to use common indent.
