How to Deal With a System Call Losering Problem
Losering means making the program counter go to user mode. The idea here is like You need to do this complicated mechanism inside to make sure you bring the program back So it can finally do this system call again because the first time it didn't work What we are told is that the MIT person didn't see anything in unix that did this complicated logic and New Jersey guy says yeah, they don't do it Instead every single time you make a system call It will just tell you did it succeed or not and you have to deal with it.
