SYS_rename may be unavailable on architectures such as aarch64 and riscv. rename can be implemented in terms of SYS_rename, SYS_renameat, or SYS_renameat2. I don't have a full picture of the history here, but it seems that SYS_renameat might also be unavailable on some platforms. `man 2 rename` mentions that SYS_renameat2 was added in Linux 3.15. We don't need to support such ancient kernel versions prior. Link: #84980 Link: #85068
