Mount point information

Fields

id: MountId

Unique mount ID

mount_type: MountType

Type of mount

path: String

Mount path (relative to parent mount)

root: VfsEntryRef

Root entry of the mounted filesystem

parent: Option<Weak<MountPoint>>

Parent mount (weak reference to avoid cycles)

parent_entry: Option<VfsEntryRef>

Parent entry (strong reference to the VFS entry at the mount point to ensure it stays alive)

children: Arc<RwLock<BTreeMap<u64, Arc<MountPoint>>>>

Child mounts: shared map of VfsEntry ID to MountPoint
