When a sysadmin wishes to monitor module unloading with a syscall
rule such as:
-a always,exit -F arch=x86_64 -S delete_module -F key=mod-unload
the SYSCALL record doesn't tell us what module was requested for unloading.
Use the new KERN_MODULE auxiliary record to record it.
The SYSCALL record result code will list the return code.
