From d5a7df0649fa6a1e7800785d760e2c7d7a3204de Mon Sep 17 00:00:00 2001 From: Tao Ma Date: Mon, 10 May 2010 18:09:47 +0800 Subject: ocfs2: Reset xattr value size after xa_cleanup_value_truncate(). In ocfs2_prepare_xattr_entry, if we fail to grow an existing value, xa_cleanup_value_truncate() will leave the old entry in place. Thus, we reset its value size. However, if we were allocating a new value, we must not reset the value size or we will BUG(). This resolves oss.oracle.com bug 1247.
