Struct btrfs_diskformat::RootRef

#[repr(C, packed)]pub struct RootRef {
    pub dirid: U64<LE>,
    pub sequence: U64<LE>,
    pub name_len: U16<LE>,
}

References a subvolume filesystem tree root. This is used for both forward and backward root references.

The name of the tree is stored after the end of the struct.

Fields

dirid: U64<LE>

The subtree ID.

sequence: U64<LE>

The directory sequence number of the subtree entry.

name_len: U16<LE>

The length of the subtree name, stored after this field.
