From: Ryusuke Konishi @ 2016-06-02 13:58 UTC (permalink / raw)
To: Andrew Morton; +Cc: linux-nilfs, LKML, Ryusuke Konishi
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.

From: Ryusuke Konishi @ 2016-06-02 13:58 UTC (permalink / raw)
To: Andrew Morton; +Cc: linux-nilfs, LKML, Ryusuke Konishi
Use nilfs_msg() to output warning messages and get rid of
nilfs_warning() function. This also removes function names from the
messages unless we embed them explicitly in format strings. Instead,
some messages are revised to clarify the context.
