Make __thrsleep(2) and __thrwakeup(2) MP-safe Threads in __thrsleep(2) are tracked using queues, one queue per each process for synchronization between threads of a process, and one system-wide queue for the special ident -1 handling. Each of these queues has an associated rwlock that serializes access. The queue lock is released when calling copyin() and copyout() in thrsleep(). This preserves the existing behaviour where a blocked copy operation does not prevent other threads from making progress. Tested by anton@, claudio@ OK anton@, claudio@, tedu@, mpi@ |
