The patch titled
Subject: nilfs2: reduce bare use of printk() with nilfs_msg()
has been removed from the -mm tree. Its filename was
nilfs2-reduce-bare-use-of-printk-with-nilfs_msg.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Ryusuke Konishi <konishi.ryusuke@xxxxxxxxxxxxx>
Subject: nilfs2: reduce bare use of printk() with nilfs_msg()
Replace most use of printk() in nilfs2 implementation with nilfs_msg(),
and reduce the following checkpatch.pl warning:
"WARNING: Prefer [subsystem eg: netdev]_crit([subsystem]dev, ...
then dev_crit(dev, ... then pr_crit(... to printk(KERN_CRIT ..."
This patch also fixes a minor checkpatch warning "WARNING: quoted string
split across lines" that often accompanies the prior warning, and amends
message format as needed.
