Yes, I realized it in https://sourceware.org/pipermail/libc-alpha/2024- July/157975.html and 2.40 should be fine. But the __NR_* constants will be there once we run update-syscall-lists.py, so we still need to handle the issue in the Glibc 2.41 dev cycle. -- Xi Ruoyao <xry111@xxxxxxxxxxx> School of Aerospace Science and Technology, Xidian University
