Subject: fs/ext3/super.c: Use printf extension %pV
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=99fbb1e2af5da27d3ee75c2e421712fe9d083fb6;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

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.
