From: Theodore Ts'o Subject: [PATCH 3/6] ext4: Rename ext4_get_blocks_wrap() to be ext4_get_blocks() Date: Tue, 12 May 2009 18:48:49 -0400 Message-ID: <1242168532-1063-4-git-send-email-tytso@mit.edu> References: <1242168532-1063-1-git-send-email-tytso@mit.edu> <1242168532-1063-2-git-send-email-tytso@mit.edu> <1242168532-1063-3-git-send-email-tytso@mit.edu> Cc: Theodore Ts'o To: Ext4 Developers List Return-path: Received: from THUNK.ORG ([69.25.196.29]:44285 "EHLO thunker.thunk.org" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1750974AbZELWs4 (ORCPT ); Tue, 12 May 2009 18:48:56 -0400 In-Reply-To: <1242168532-1063-3-git-send-email-tytso@mit.edu> Sender: linux-ext4-owner@vger.kernel.org List-ID: Another function rename for clarity's sake. The _wrap prefix simply confuses people, and didn't add much people trying to follow the code paths.
