ocfs2/xattr: Reserve meta/data at the beginning of ocfs2_xattr_set.
In ocfs2 xattr set, we reserve metadata and clusters in any place they are needed. It is time-consuming and ineffective, so this patch try to reserve metadata and clusters at the beginning of ocfs2_xattr_set. Signed-off-by: Tao Ma <tao.ma@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
