[PATCH v8 0/5] xfs: Allow pquota and gquota to be used together

[Chandra Seetharaman]

Hello All,

This is the version 8 of the changes to allow pquota and gquota to be used
together.

Patchset applies cleanly on top of 7dfbcbefad4b24d9822d04dbd7b5dd5c3fd45076
in xfs git tree.

Ran latest xfstests against it.

Changes from version 7 to version 8:
 - Rebased to the current code.
 - Modified code to use the new pquotino field in version 5
   of the superblock.

Version 7 can be found at:
http://oss.sgi.com/archives/xfs/2013-03/msg00671.html

Changes from version 6 to version 7:
 - Made all the changes suggested by Dave Chinner
 - Added padding to fs_quota_stat, which made the new
   data structure field ordering different from the old data
   structure field ordering. So, copied the old version
   to be _v1 version and used that if old version of data
   structure was provided from user space.

Version 6 can be found at:
http://oss.sgi.com/archives/xfs/2012-07/msg00286.html

Changes from version 5 to version 6:
- Use radix tree instead of hash table

Version 5 can be found at:
http://oss.sgi.com/archives/xfs/2012-03/msg00310.html

Changes fron version 4 to version 5:
rebase with the current tree one simple change.

Version 4 can be found at
http://oss.sgi.com/archives/xfs/2012-02/msg00528.html

Changes from version 3 to version 4:
- Remove save_flags with storing the value (in to superblock) 
  based on field type info
- fix checkpatch.pl warnings and errors

Version 3 of the posting can be found at
http://oss.sgi.com/archives/xfs/2012-01/msg00309.html

Changes from version 2 to version 3:
 - hash table for pquota is added.
 - changes to apply cleanly with the latest tree

version 2 of the posting can be found at
http://oss.sgi.com/archives/xfs/2011-10/msg00470.html

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()
