Subject: [PATCH v2 04/13] btrfs-progs: Fix Wempty-body warning
Date: Wed,  5 Dec 2018 14:40:09 +0800
Message-ID: <20181205064018.27755-5-wqu@suse.com> (raw)
In-Reply-To: <20181205064018.27755-1-wqu@suse.com>

messages.h:49:24: warning: suggest braces around empty body in an 'if' statement [-Wempty-body]
    PRINT_TRACE_ON_ERROR;    \

Just extra braces would solve the problem.
