I am working on an extension to Solaris scheduler and I find myself needing to acquire locks on TWO kthread structs (via thread_lock(t)) at once, i.e., in a single function. I have not seen this done anywhere in Solaris kernel: usually one thread lock is held at a time, and so I am concerned that getting two locks on different kthread structs might lead to a deadlock.
Do you know if two kthread locks are acquired simultaneously anywhere in the Solaris kernel and if so what locking protocol (if any) is followed? Or should I try to solve my problem without holding two thread locks?
