Nominally, KeDelayExecutionThread. However, in many cases there are
better ways to handle this, such as using a timer. What are you waiting
for?

Depending on the amount of time you need to wait, you can use KeStallExecutionProcessor or KeDelayExecutionThread. Please read the documentation of both the APIs carefully.
Having said, be *very* careful in putting sleep()'s in a driver. Most of the times there’s a better solution than putting a sleep in kernel mode. If possible sleep in user mode. A sleep in the wrong place in a driver can kill the performance of your machine. What problem are you trying to solve with a sleep?
Have a nice day

That is clear. Why do you think you need to wait? What are you waiting for? for instance, are you initializing a piece of hardware and you need to wait a period of time? Approximately how long do you want to wait? In what context (pnp start device, work item, timer, etc) do you want to wait?

Sorrry,
Desire to hope that a list of memory nodes is released, these nodes are in
a thread…

That would appear to me to be a broken design. Why not set some state in a shared context in the thread that you think should sleep and then in the thread which releases the nodes, it checks the state and does the right thing. Sleeping for this scenario is not really compatible with how drivers should be written.
