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

in arch/arm64/include/asm/unistd32.h defined :
__SYSCALL(135, sys_sysfs)
So I used 135 to test sysfs, I straced sysfs01,
the syscall called rt_sigprocmask not sysfs:
rt_sigprocmask(SIG_UNBLOCK, [], 0x8, 0) = -1 EINVAL (Invalid argument)

It's disabled of course, because we don't support ancient libc
implementations. No modern Linux port has this.

__NR__lchown32?__NR_lstat?__NR__sysctl?__NR_vserver have similar problems.
Dose aarch64 support those system call?
How I distinguish the ancient libc implementations.

You can find the syscalls from include/uapi/asm-generic/unistd.h.
Please note below definitions are not defined on aarch64.
__ARCH_WANT_SYSCALL_NO_AT
__ARCH_WANT_SYSCALL_NO_FLAGS
__ARCH_WANT_SYSCALL_DEPRECATED
