[GIT PULL] Quota improvements and minor cleanups

[Jan Kara]

  Hello Linus,

  could you please pull from

git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs.git for_linus

  to get 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.

Top of the tree is fdf2657bc81b. The full shortlog is:

Anton Blanchard (1):
      quota: Add log level to printk

Jan Kara (12):
      quota: Remove const from function declarations
      quota: Allow each filesystem to specify which quota types it supports
      gfs2: Set allowed quota types
      xfs: Set allowed quota types
      quota: Use function to provide i_dquot pointers
      ext2: Convert to private i_dquot field
      ext3: Convert to private i_dquot field
      ext4: Convert to private i_dquot field
      ocfs2: Convert to private i_dquot field
      reiserfs: Convert to private i_dquot field
      jfs: Convert to private i_dquot field
      vfs: Remove i_dquot field from inode

Markus Elfring (3):
      jbd: Deletion of an unnecessary check before the function call "iput"
      udf: Deletion of unnecessary checks before the function call "iput"
      udf: One function call less in udf_fill_super() after error detection
