Why getting warning: process `xsm_group_manag' used the deprecated sysctl system call ?

Issue

• We are getting following messages in /var/log/messages

  Feb 17 16:11:25 reds kernel: warning: process `xsm_group_manag' used the deprecated sysctl system call with 1.52.
  

• If it is truly deprecated, what would be the new replacement call to obtain kernel setting for determining if core file is configured to have a PID extension? This call below is what caused the warning.

  int oldval = 0;
  size_t oldlenp = sizeof(int);
  
  int name[] = { CTL_KERN, KERN_CORE_USES_PID };
  struct __sysctl_args args;
  memset(&args, 0, sizeof(struct __sysctl_args));
  syscall(SYS__sysctl, &args);
