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
