Struct HugePageStatus 

pub struct HugePageStatus {
    pub enabled: bool,
    pub advised_bytes: u64,
    pub failed_calls: u64,
    pub anon_huge_bytes: Option<u64>,
}

What the huge-page advice of this process achieved.

Fields

enabled: bool

The advice is on (WARM_QGRAPH_HUGEPAGES unset or non-zero).

advised_bytes: u64

Bytes for which madvise(MADV_HUGEPAGE) succeeded.

failed_calls: u64

madvise calls that failed (each falls back to base pages; nothing else changes).

anon_huge_bytes: Option<u64>

AnonHugePages of the whole process from /proc/self/smaps_rollup, whoever asked for them (the allocator may hold huge pages of its own). None where the file is unreadable (outside Linux, or a sandbox without it). VGraph::code_rows_huge_bytes gives the figure for one index’s code rows.
