// If there has been no garbage collection at all, the heap profile reports
// all known allocations. This exception helps mainly in programs running
// without garbage collection enabled, usually for debugging purposes.

// The heap profile tracks both the allocation sites for all live objects in

// total container resource requests and to the total container limits which have a
// non-zero quantity. The caller may avoid allocations of resource lists by passing
// a requests and limits list to the function, which will be cleared before use.
// This method is the same as v1resource.PodRequestsAndLimits but avoids allocating in several
// scenarios for efficiency.
