you can't. there is no concept of TLS in kernel. you can create your own
table on the side using the current thread ID + current IRQL as the lookup,
but b/c you can run in any arbitrary thread context for DPCs and potentialy
incoming I/O, TLS doesn't make much sense. what problem are u trying to
solve?
