/*
 * This function forces all errors to -EIO for consistency with its
 * predecessor, ocfs2_bread().  We haven't audited what returning the
 * real error codes would do to callers.  We log the real codes with
 * mlog_errno() before we squash them.

static int ocfs2_read_dir_block(struct inode *inode, u64 v_block,
                                struct buffer_head **bh, int flags)

According to ocfs2_read_dir_block comments, caller don't care the err value, func will log it.

So is this patch ok? :)

Thanks
