Changes from version 1 to version 2:

 - Created a new prep patch to accomodate some generic changes that ease
   the later patches.
 - Created a new patch to add a new field qs_pquota to fs_quota_stat
   with appropriate versioning changes
 - Changed the logic to allow XFS_OQUOTA.* flags to be allowed only in
   the older versions.
 - Changed couple of places where PQUOTA checking was on the else if
   construct so as to allow both GQUOTA and PQUOTA in those places.
 - Fixed comments in xfs_quota.h to reflect the current changes.
 - Changed the name of the macro XFS_SB_VERSION2_SEPER_PQUOTA to 
   XFS_SB_VERSION2_NO_OQUOTA
 - got rid of the macros XFS_MOUNT_QUOTA_SET1 and XFS_MOUNT_QUOTA_SET2
 - added a new inline function xfs_inode_dquot(ip, type) to simplify
   the error path in xfs_qm_dqget()
 - got rid of the macro XFS_IS_THIS_QUOTA_OFF
 - added comment to explain why sb_qflags is saved and restored in 
   xfs_sb_to_disk()

Thanks & Regards,
