Hello!
I am taking an operating systems course where we have a bonus assignment of modifying a linux kernel system call. The suggested modification was to "Make use of the Linux Netpoll API in the write syscall." but I can't find the documentation for how to send data using a file descriptor and the netpoll api. So I want to modify some other system call but have a hard time finding a suitable modification to do.
Any suggestions for an intersting modification to a system call that I could do?
