[Ryusuke Konishi]

Hi Andrew,

Please queue the following changes for the next merge window:

Ryusuke Konishi (8):
      nilfs2: hide function name argument from nilfs_error()
      nilfs2: add nilfs_msg() message interface
      nilfs2: embed a back pointer to super block instance in nilfs object
      nilfs2: reduce bare use of printk() with nilfs_msg()
      nilfs2: replace nilfs_warning() with nilfs_msg()
      nilfs2: emit error message when I/O error is detected
      nilfs2: do not use yield()
      nilfs2: refactor parser of snapshot mount option

* Brief Summary

This series revises message interface of nilfs, and cleans a few
more checkpatch warnings.

>      nilfs2: hide function name argument from nilfs_error()

This simplifies argument of nilfs_error() output routine.

>      nilfs2: add nilfs_msg() message interface
>      nilfs2: embed a back pointer to super block instance in nilfs object
>      nilfs2: reduce bare use of printk() with nilfs_msg()
>      nilfs2: replace nilfs_warning() with nilfs_msg()

These add a new message routine "nilfs_msg()", use it to reduce bare
use of printk(), and also unify nilfs_warning() output routine to it.

>      nilfs2: emit error message when I/O error is detected

This helps to distinguish whether a file system error comes from the
underlying device or not by having io routines of nilfs output error
messages when they detect an I/O error.

>      nilfs2: do not use yield()
>      nilfs2: refactor parser of snapshot mount option

These remove two remaining checkpatch warnings.


Thanks,
Ryusuke Konishi
