This var is currently useless, as it's apparent from reading the code. Until
2.6.11 it was used in some code related to jail mode, in the same proc.:
if(jail){
while(!reading) sched_yield();
}
jail mode has been dropped, together with that use, so let's finish dropping
this.
Also, remove some other useless definitions I met.
