arm64: dose arm64 support the sysfs system call?

[wangyufen]

Hi,

I did ltp test on arm64, the sysfs testcases failed:

    sysfs01     0  TWARN  :  This test can only run on kernels that support the sysfs system call

because the __NR_sysfs didn't define in aarch64

Dose anyone know what number the sysfs system call is in aarch64?


Thanks,
Wang
