+Subject: xfs: only assert new size for datafork during truncate extents
+
+From: Long Li <leo.lilong@huawei.com>
+
+commit e942498385bf80f4d6d075b47174035545eb6a2e upstream.
+
+The assertion functions properly because we currently only truncate the
+attr to a zero size. Any other new size of the attr is not preempted.
+Make this assertion is specific to the datafork, preparing for
+subsequent patches to truncate the attribute to a non-zero size.
