subr_trap.c
sys/sys proc.h resourcevar.h
Log:
- Move p_cpulimit to struct proc from struct plimit and protect it with
sched_lock. This means that we no longer access p_limit in mi_switch()
and the p_limit pointer can be protected by the proc lock.
- Remove PRS_ZOMBIE check from CPU limit test in mi_switch(). PRS_ZOMBIE
processes don't call mi_switch(), and even if they did there is no longer
the danger of p_limit being NULL (which is what the original zombie check
was added for).
- When we bump the current processes soft CPU limit in ast(), just bump the
private p_cpulimit instead of the shared rlimit. This fixes an XXX for
some value of fix. There is still a (probably benign) bug in that this
code doesn't check that the new soft limit exceeds the hard limit.
