parentscore: Move _Thread_blocking_operation_Cancel() (diff)
downloadrtems-688fbc4401ad89abb2ecdd64c8137297ac5e07ba.tar.bz2
score: Move _Thread_queue_Extract()
Move _Thread_queue_Dequeue(). We need all or no thread queue functions so it makes no sense to have them in separate modules. One module enables compiler optimizations without link-time optimization. Make _Thread_blocking_operation_Finalize() static since it is use now only in one module.
