From: Theodore Ts'o Subject: [PATCH, RFC] ext4: remove ext4_new_meta_block() Date: Sun, 7 Dec 2008 14:33:53 -0500 Message-ID: <1228678434-14707-2-git-send-email-tytso@mit.edu> References: <1228678434-14707-1-git-send-email-tytso@mit.edu> Cc: Theodore Ts'o To: Ext4 Developers List Return-path: Received: from www.church-of-our-saviour.org ([69.25.196.31]:41271 "EHLO thunker.thunk.org" rhost-flags-OK-OK-OK-FAIL) by vger.kernel.org with ESMTP id S1752179AbYLGUbv (ORCPT ); Sun, 7 Dec 2008 15:31:51 -0500 In-Reply-To: <1228678434-14707-1-git-send-email-tytso@mit.edu> Sender: linux-ext4-owner@vger.kernel.org List-ID: There were only two one callers of the function ext4_new_meta_block(), which just a very simpler wrapper function around ext4_new_meta_blocks(). Change those two functions to call ext4_new_meta_blocks() directly, to save code and stack space usage.
