Subject: [PATCH 0/3] nilfs2 lockdep warning fixes

Hi Andrew,

please consider applying the following changes to -mm tree.

Ryusuke Konishi (3):
  nilfs2: fix lockdep warnings in page operations for btree nodes
  nilfs2: fix lockdep warnings during disk space reclamation
  nilfs2: get rid of nilfs_mapping_init()

The first two are to resolve the lockdep warning issue, and the last
one is the accompanying cleanup and low priority.

The merge window is already open, but this is for the reported issues,
so I'll send it without waiting at this point when tests have passed.

Based on your comment, this series solves the issue by separating
inode object as needed.  Since I was worried about the impact of the
object composition changes, I tested the series carefully not to cause
regressions especially for delicate functions such like disk space
reclamation and snapshots.

Thanks,
Ryusuke Konishi
