[PATCH 0/3 v2] Q_GETNEXTQUOTA support

[Jan Kara <jack@xxxxxxx>]

Hello,

the patch set below adds support for VFS quotas for Q_GETNEXTQUOTA quotactl
and thus repquota(8) doesn't have to iterate over /etc/passwd or LDAP database
to report all quota limits. ext2, ext4, reiserfs, jfs, and ocfs2 support this
quotactl (and Q_XGETNEXTQUOTA as well) after applying this patch set. XFS
bits will likely get merged independently through XFS tree. If nobody objects,
I'll push these patches to my tree in a few days.

Changes since v2:
* Added get_next_id() operation to dquot_operations to allow for cleaner
  support in OCFS2
* Added OCFS2 support
