## Summary add a reference count to the TCB to prevent it from being deleted. To replace the large lock with smaller ones and reduce the large locks related to the TCB, in many scenarios, we only need to ensure that the TCB won't be released instead of locking, thus reducing the possibility of lock recursion. ## Impact sched ## Testing test in hardware esp32s3-devkit:nsh user_main: scheduler lock test sched_lock: Starting lowpri_thread at 97 sched_lock: Set lowpri_thread priority to 97 sched_lock: Starting highpri_thread at 98 sched_lock: Set highpri_thread priority to 98 sched_lock: Waiting... sched_lock: PASSED No pre-emption occurred while scheduler was locked. sched_lock: Starting lowpri_thread at 97 sched_lock: Set lowpri_thread priority to 97 sched_lock: Starting highpri_thread at 98 sched_lock: Set highpri_thread priority to 98 sched_lock: Waiting... sched_lock: PASSED No pre-emption occurred while scheduler was locked. sched_lock: Finished End of test memory usage: VARIABLE BEFORE AFTER ======== ======== ======== arena 5d8bc 5d8bc ordblks 7 6 mxordblk 548a0 548a0 uordblks 5014 5014 fordblks 588a8 588a8 Final memory usage: VARIABLE BEFORE AFTER ======== ======== ======== arena 5d8bc 5d8bc ordblks 1 6 mxordblk 59238 548a0 uordblks 4684 5014 fordblks 59238 588a8 user_main: Exiting ostest_main: Exiting with status 0 nsh> u nsh: u: command not found nsh> nsh> nsh> nsh> uname -a NuttX 12.11.0 ef91333e3ac-dirty Dec 10 2025 16:11:04 xtensa esp32s3-devkit nsh> -- This is an automated message from the Apache Git Service.
