Dear
I have referenced your project, URCU (Userspace RCU), on GitHub, which is based on the QSBR model. However, I noticed that when using it in user mode, it makes system calls to enter the kernel. Could you please provide guidance on how to address this issue? I aim to achieve a pure user-mode implementation. Specifically, I would appreciate any insights or suggestions on avoiding system calls while still maintaining the functionality of the QSBR model in user space. Thank you very much for your time and assistance.
