Struct VmallocAttr 

pub struct VmallocAttr {
    pub task_id: u64,
    pub pid: u32,
    pub tid: u32,
    pub silo_id: u32,
    pub size: usize,
    pub alloc_seq: u64,
    pub caller_file: &'static str,
    pub caller_line: u32,
    pub caller_column: u32,
}

Attribution snapshot captured at vmalloc time.

Stored inside each live allocation node so that dump_live_allocations() can attribute each mapping to a task and silo without external state.

Designed for post-mortem leak analysis:

• alloc_seq gives ordering (smallest = oldest live alloc).
• pid/tid/silo_id identify the requesting workload.
• size is the requested byte count, not the page-rounded value.

Fields

task_id: u64

Scheduler task id (0 = kernel or pre-scheduler context).

pid: u32

PID of the requesting task (0 = kernel or pre-scheduler context).

tid: u32

TID of the requesting task.

silo_id: u32

Silo that owns the task (0 = kernel / silo lookup failed / not in silo).

size: usize

Requested allocation size in bytes (before page-rounding).

alloc_seq: u64

Monotonic per-boot sequence number (see VMALLOC_ALLOC_SEQ).

caller_file: &'static str

Best-effort callsite file of the allocator request.

caller_line: u32

Best-effort callsite line of the allocator request.

caller_column: u32

Best-effort callsite column of the allocator request.
