Merge branch 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs-2.6 

* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs-2.6:
  quota: Convert quota statistics to generic percpu_counter
  ext3 uses rb_node = NULL; to zero rb_root.
  quota: Fixup dquot_transfer
  reiserfs: Fix resuming of quotas on remount read-write
  pohmelfs: Remove dead quota code
  ufs: Remove dead quota code
  udf: Remove dead quota code
  quota: rename default quotactl methods to dquot_
  quota: explicitly set ->dq_op and ->s_qcop
  quota: drop remount argument to ->quota_on and ->quota_off
  quota: move unmount handling into the filesystem
  quota: kill the vfs_dq_off and vfs_dq_quota_on_remount wrappers
  quota: move remount handling into the filesystem
  ocfs2: Fix use after free on remount read-only

Fix up conflicts in fs/ext4/super.c and fs/ufs/file.c
