Subject: [PATCH 6/8] xfs: add DAX truncate support
Date: Fri, 29 May 2015 09:45:53 +1000 [thread overview]
Message-ID: <1432856755-7859-7-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1432856755-7859-1-git-send-email-david@fromorbit.com>
From: Dave Chinner <dchinner@redhat.com>
When we truncate a DAX file, we need to call through the DAX page
truncation path rather than through block_truncate_page() so that
mappings and block zeroing are all handled correctly. Otherwise,
truncate does not need to change.
