Subject: [PATCH 1/6] xfs: remove XBF_DONE flag wrapper macros
Date: Fri,  5 Feb 2016 11:37:58 +1100	[thread overview]
Message-ID: <1454632683-20543-2-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1454632683-20543-1-git-send-email-david@fromorbit.com>

From: Dave Chinner <dchinner@redhat.com>

They only set/clear/check a flag, no need for obfuscating this
with a macro.
