From 99fbb1e2af5da27d3ee75c2e421712fe9d083fb6 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Tue, 9 Nov 2010 10:18:05 -0800 Subject: [PATCH] fs/ext3/super.c: Use printf extension %pV Using %pV reduces the number of printk calls and eliminates any possible message interleaving from other printk calls.
