DESCRIPTION

All the blk units are in BBs (Basic Blocks) of 512 bytes.

.d_version: Version of this structure.

.d_flags: XFS_{USER,PROJ,GROUP}_QUOTA

.d_fieldmask: Field specifier.

.d_id: User, project, or group ID.

.d_blk_hardlimit: Absolute limit on disk blocks.

.d_blk_softlimit: Preferred limit on disk blocks.

.d_ino_hardlimit: Maximum # allocated inodes.

.d_ino_softlimit: Preferred inode limit.

.d_bcount: # disk blocks owned by the user.

.d_icount: # inodes owned by the user.

.d_itimer: Zero if within inode limits; if not, we refuse service.

.d_btimer: Similar to above; for disk blocks.

.d_iwarns: # warnings issued with respect to # of inodes.

.d_bwarns: # warnings issued with respect to disk blocks.

.d_padding2: Padding; reserved for future use.

.d_rtb_hardlimit: Absolute limit on realtime (RT) disk blocks.

.d_rtb_softlimit: Preferred limit on RT disk blocks.

.d_rtbcount: # realtime blocks owned.

.d_rtbtimer: Similar to above; for RT disk blocks.

.d_rtbwarns: # warnings issued with respect to RT disk blocks.

.d_padding3: Padding; reserved for future use.

.d_padding4[8]: Yet more padding.
