Hi,

Please review the above patch, which can be found on the link below:
https://lore.kernel.org/all/20221211092820.85527-1-code@xxxxxxxx

This was encountered before the patch adding missing <sys/syscall.h>
was applied, which just means that I went into the code path under
#ifndef __NR_mount_setattr, and encountered the error.

Thanks,
Siddh
