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

Pull quota updates from Jan Kara:
 "Quota improvements and some minor cleanups.

  The main portion in the pull request are changes which move i_dquot
  array from struct inode into fs-private part of an inode which saves
  memory for filesystems which don't use VFS quotas"

* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
  udf: One function call less in udf_fill_super() after error detection
  udf: Deletion of unnecessary checks before the function call "iput"
  jbd: Deletion of an unnecessary check before the function call "iput"
  vfs: Remove i_dquot field from inode
  jfs: Convert to private i_dquot field
  reiserfs: Convert to private i_dquot field
  ocfs2: Convert to private i_dquot field
  ext4: Convert to private i_dquot field
  ext3: Convert to private i_dquot field
  ext2: Convert to private i_dquot field
  quota: Use function to provide i_dquot pointers
  xfs: Set allowed quota types
  gfs2: Set allowed quota types
  quota: Allow each filesystem to specify which quota types it supports
  quota: Remove const from function declarations
  quota: Add log level to printk
