Hello All,

This is the version 2 of the changes to allow pquota and gquota to be used
together.

Previous version of the posting can be found at
http://article.gmane.org/gmane.comp.file-systems.xfs.general/41284

Changes from the previous version:

 - 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,

chandra

Define few macros, inline functions, and change interface in
preparation for allowing pquota and gquota to be used together.

Remove incore use of XFS_OQUOTA_ENFD and XFS_OQUOTA_CHKD. Instead,
start using XFS_GQUOTA_.* XFS_PQUOTA_.* counterparts.

No changes is made to the on-disk version of the superblock yey. On-disk
copy still uses XFS_OQUOTA_ENFD and XFS_OQUOTA_CHKD.

From: Chandra Seetharaman @ 2011-10-26 21:22 UTC (permalink / raw)
  To: xfs; +Cc: Chandra Seetharaman

Add a new field to the superblock to add support for seperate pquota
with a specific version.

No change made yet to gather both project and group quota with quotactl.

Looks good, but I'd really prefer to split this up further:

 - one patch for adding xfs_inode_dquot
 - one patch for adding XFS_IS_TYPE_QUOTA_ON
   (which I'd rather make an inline and call xfs_this_quota_on)
 - one for passing the mount structure to xfs_sb_from_disk
 - one for the quota flags changes.

All of these also should have a good changelog, most importantly the flag
changes.  If you can repost just these changes relatively soon please do
so, as I have a huge series for the quota code that should go into the
3.2 tree which I need to rebase anyway, and I'd like to do it on top of
your changes.

For code you touch please always use the struct versions instead of
the typedefs for lines you change anyway or add.

Sure.

Will submit this as a separate set, so that it can go in faster.
