struct btrfs_util_subvolume_info - Information about a Btrfs subvolume.

Fields

id: u64

@id: ID of this subvolume, unique across the filesystem.

parent_id: u64

@parent_id: ID of the subvolume which contains this subvolume, or zero for the root subvolume (BTRFS_FS_TREE_OBJECTID) or orphaned subvolumes (i.e., subvolumes which have been deleted but not yet cleaned up).

dir_id: u64

@dir_id: Inode number of the directory containing this subvolume in the parent subvolume, or zero for the root subvolume (BTRFS_FS_TREE_OBJECTID) or orphaned subvolumes.

flags: u64

@flags: On-disk root item flags.

uuid: [u8; 16]

@uuid: UUID of this subvolume.

parent_uuid: [u8; 16]

@parent_uuid: UUID of the subvolume this subvolume is a snapshot of, or all zeroes if this subvolume is not a snapshot.

received_uuid: [u8; 16]

@received_uuid: UUID of the subvolume this subvolume was received from, or all zeroes if this subvolume was not received. Note that this field, @stransid, @rtransid, @stime, and @rtime are set manually by userspace after a subvolume is received.

generation: u64

@generation: Transaction ID of the subvolume root.

ctransid: u64

@ctransid: Transaction ID when an inode in this subvolume was last changed.

otransid: u64

@otransid: Transaction ID when this subvolume was created.

stransid: u64

@stransid: Transaction ID of the sent subvolume this subvolume was received from, or zero if this subvolume was not received. See the note on @received_uuid.

rtransid: u64

@rtransid: Transaction ID when this subvolume was received, or zero if this subvolume was not received. See the note on @received_uuid.

ctime: timespec

@ctime: Time when an inode in this subvolume was last changed.

otime: timespec

@otime: Time when this subvolume was created.

stime: timespec

@stime: Not well-defined, usually zero unless it was set otherwise. See the note on @received_uuid.

rtime: timespec

@rtime: Time when this subvolume was received, or zero if this subvolume was not received. See the note on @received_uuid.
