Thread-topic: Use of newer locking primitives...

Hello folks.

Has anyone taken it upon themselves to try using higher performance locking primitives, (i.e. Queued spinlocks) in our drivers? Anyone see any issues where we depend on the implementation of locking primitives, or could we just do a “drop in” (i.e. search and replace) replacement?
