Hello. I try to implement fair spinlock and put on [this.](https://github.com/TaiJuWu/nuttx/blob/1452773ead23ffa814800733db266b52cd066715/sched/semaphore/spinlock.c#L400) I try to test by this [file.](https://github.com/TaiJuWu/nuttx-apps/blob/fair_spinlock_test/examples/hello/hello_main.c) The result like this ``` Thread 6 is exiting lock 4 time. Thread 7 is enter lock 4 time. Thread 7 is exiting lock 4 time. Thread 6 is enter lock 5 time. Thread 6 is exiting lock 5 time. Thread 7 is enter lock 5 time. Thread 7 is exiting lock 5 time. Thread 8 is enter lock 1 time. Thread 8 is exiting lock 1 time. Thread 9 is enter lock 1 time. Thread 9 is exiting lock 1 time. Thread 8 is enter lock 2 time. Thread 8 is exiting lock 2 time. Thread 9 is enter lock 2 time. Thread 9 is exiting lock 2 time. Thread 8 is enter lock 3 time. Thread 8 is exiting lock 3 time. Thread 9 is enter lock 3 time. Thread 9 is exiting lock 3 time. Thread 8 is enter lock 4 time. Thread 8 is exiting lock 4 time. ``` But I only test on RR scheduler and I am not sure my implementation is correct or not. So I hope I can get some suggestions from community. If you have any suggestions, i would be very grateful. PS. I did't implement preemptive for this fair spinlock. -- This is an automated message from the Apache Git Service.
