A very good patch! It would be even better if it covered ALL syscalls either without parameter or with all int-like parameters. I believe this table can be very useful to you, for the purpose of identifying such syscalls, and completing your patch: https://blog.rchapman.org/posts/Linux_System_Call_Table_for_x86_64/ Regards,
