Subject: [PATCH 08/13] NFSv4: Extend fattr bitmaps to support all 3 words
Date: Wed, 22 May 2013 12:50:41 -0400 [thread overview]
Message-ID: <1369241446-7680-9-git-send-email-SteveD@redhat.com> (raw)
In-Reply-To: <1369241446-7680-1-git-send-email-SteveD-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>
From: David Quigley <dpquigl-a7DkhOHRHBuN9aS15agKxg@public.gmane.org>
The fattr handling bitmap code only uses the first two fattr words sofar. This
patch adds the 3rd word to being sent but doesn't populate it yet.
