This appears impossible with the current set of KPI.
Looking at lf_advlock as a model, a VFS would look through struct proc uu_wchan to see if a a particular process is waiting on a lock held by the current process.
This is not possible given the set of KPI.
Is there another way to detect deadlocks?
