[GIT PULL] nilfs2 updates for 2.6.35

[Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>]

Hi Linus,

please pull from

  git://git.kernel.org/pub/scm/linux/kernel/git/ryusuke/nilfs2.git for-linus

to receive the following updates from nilfs2 tree.  Mostly cleanups
and minor fixes.  There are a few minor changes:

 * A mount option change that makes read-only remount the default of
   when critical metadata inconsistency was found.
 * Enlarged filesystem label.
 * An extension of log header format in order to ensure that
   diagnostic tool or fsck obtains checkpoint number from on-disk
   logs.

But no influential change is made.

Thanks,

Ryusuke Konishi
