no successfully descheduled or never scheduled task has it set.

Need resched confused the skip_clock_update logic, which assumes
that the next call to update_rq_clock() will come nearly immediately
after being set.  Make the optimization robust against the waking

the current task has not been dequeued before setting the flag,
since it is that useless clock update we're trying to save, and
clear unconditionally in schedule() proper instead of conditionally

 'cwe': ['CWE-122', 'CWE-787'], 'message': 'Fix TensorKey hash function.

The original hash function only used total estimated `AllocatedBytes()`, which (a) is an estimate per tensor, and (b) is a very poor hash function for constants (e.g. `int32_t`).
It also tried to access individual tensor bytes through `tensor.data()` of size `AllocatedBytes()`.  This led to ASAN failures because the `AllocatedBytes()` is an estimate of total bytes allocated by a tensor, including any pointed-to constructs (e.g. strings), and does not refer to contiguous bytes in the `.data()` buffer.  We couldn't use this byte vector anyways, since types like `tstring` include pointers, whereas we need to hash the string values themselves.

Modified the hash function to more closely mirror the `==` operator.  This correctly handles `tstring` and any numeric types that do have contiguous storage.  Other types are currently left as unimplemented.
