Subject: nilfs2: Convert __nilfs_msg to integrate the level and format
Reduce object size a bit by removing the KERN_<LEVEL> as a separate
argument and adding it to the format string.
Reduce overall object size by about ~.5% (x86-64 defconfig w/ nilfs2)
old:
$ size -t fs/nilfs2/built-in.a | tail -1
191738 8676 44 200458 30f0a (TOTALS)
new:
$ size -t fs/nilfs2/built-in.a | tail -1
190971 8676 44 199691 30c0b (TOTALS)
