 * @buf:       Input. Userspace pointer (encoded as __u64 to keep the layout
 *             stable between 32-bit and 64-bit callers) to the destination
 *             buffer that receives the metric table.
 * @size:      Input. Size in bytes of the buffer pointed to by @buf, and the
 *             number of bytes copied out on success.  Must be non-zero and no
 *             larger than the metric table size firmware reports for this
 *             socket; a larger value is rejected with -EINVAL rather than
 *             short-written.  A smaller value returns the leading @size bytes
 *             of the snapshot.  The kernel does not write this field back.
 * @sock_ind:  Input. Socket index from which the metric table is read.
 * @reserved:  Reserved for future use.  Callers should set this to zero;
 *             future kernels may begin interpreting the field, so passing
 *             a non-zero value today is not forwards compatible.
 *
 * Placing @buf first lets all fields fall on their natural alignment under
 * the surrounding #pragma pack(4), so the struct is a tight 16 bytes with
 * the same wire layout on 32-bit and 64-bit userspace.
 *
 * The metric table layout depends on the HSMP protocol version reported by
 * firmware, which userspace can read from the protocol_version sysfs
 * attribute.  Protocol version 6 uses struct hsmp_metric_table, so callers on
 * that version pass sizeof(struct hsmp_metric_table).  Later version metrics
 * table layout is documented in the Public PPR.
