[PATCH] ps shows wrong ppid

[PATCH] ps shows wrong ppid

/proc shows the wrong PID as parent in the following case

Process A creates Threads 1 & 2 (using pthread_create) Thread 2 then forks
and execs process B getppid() for Process B shows Process A (rightly) as
parent, however /proc/B/status shows Thread 3 as PPid (incorrect).
