From mboxrd@z Thu Jan 1 00:00:00 1970 From: Joe Perches Subject: [PATCH] fs/ext2/super.c: Use printf extension %pV Date: Tue, 09 Nov 2010 10:16:03 -0800 Message-ID: <1289326563.1823.85.camel@Joe-Laptop> Mime-Version: 1.0 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: 7bit Cc: linux-ext4@vger.kernel.org, linux-kernel@vger.kernel.org To: Jan Kara Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: linux-ext4.vger.kernel.org Using %pV reduces the number of printk calls and eliminates any possible message interleaving from other printk calls.
