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
