Can you please help me develop a syscall for kernel to return the pid of the process that has the longest descendants path leading to a process that has no children? I am supposed to return the length of this path. Skip the process with the pid identifier specified in the parameter.
I managed to install phoenix in my ubuntu system. I was able to do the maxChildren syscall, but I have no idea how to implement the longestDescendant syscall.
For now I only have: int syscall_longestDescendants(void * unstack) { }
