Struct TimelineCapture 

pub struct TimelineCapture<'a> {
    pub records: &'a [u8],
    pub drops: u64,
}

Capture handle for the freeze coordinator’s drain of the timeline_events BPF ringbuf.

At dump time the coordinator constructs this with the drained raw bytes (concatenated 40-byte records, in ringbuf order) plus the BSS-side drop count. The dump consumer parses the buffer into TimelineEvent values. This capture is not yet consumed by the dump pipeline; the BSS-side drop count is surfaced today via super::dump::ProbeBssCounters::timeline_drops (reached through super::dump::FailureDumpReport::probe_counters).

Fields

records: &'a [u8]

Raw concatenated record bytes drained from the timeline_events ringbuf. Length must be a multiple of size_of::<TimelineEventRaw>() (40); trailing partial records are silently dropped at parse time.

drops: u64

KTSTR_PCPU_TIMELINE_DROPS per-CPU slot (summed across CPUs) at drain time. Non-zero indicates the BPF producer hit a full ringbuf and dropped the newest event(s) on submit.
