Soft token staleness question

[Venkatesh Srinivas <me@xxxxxxxxxxxxxxxxxxx>]

Hi,

Why is lwkt_token_is_stale if 0-ed out?

If I understand the motivation behind tokens, higher level code can take it an call lower level code which can block. But without the ability to check staleness, how you know if lower level code blocked and allowed your assumptions made under the token earlier to be invalidated?

Thanks,
