Hi Andrew,
Please queue the following changes for the next merge window:
Eric Biggers (1):
nilfs2: only call unlock_new_inode() if I_NEW
Joe Perches (2):
nilfs2: Convert __nilfs_msg to integrate the level and format
nilfs2: Use a more common logging style
In this series,
> nilfs2: only call unlock_new_inode() if I_NEW
fixes wrong unlock_new_inode() call and related WARNING which can be
triggered from error paths of nilfs_new_inode().
> nilfs2: Convert __nilfs_msg to integrate the level and format
> nilfs2: Use a more common logging style
reduce object size and use more common kernel logging styles.
Thanks,
Ryusuke Konishi

1.8.3.1
From: Joe Perches <[email protected]>
Add macros for nilfs_<level>(sb, fmt, ...) and convert the uses of
'nilfs_msg(sb, KERN_<LEVEL>, ...)' to 'nilfs_<level>(sb, ...)' so nilfs2
uses a logging style more like the typical kernel logging style.
Miscellanea:
o Realign arguments for these uses

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)
