Subject: [Q] why switch_exec_pids() changes thread group leader pid?
Date: Mon, 20 Sep 2004 15:29:47 +0400 [thread overview]
Message-ID: <414EBF2B.5090909@sw.ru> (raw)
Hello,
I've been looking through switch_exec_pids() function and found that it
changes thread group leader PID/TGID. Is it really a good idea to change
pid of the process during it's lifetime? I could understand if it was
happenning in the context of that process, but pid changes everytime a
thread calls do_execve().
As far as I can see, leader doesn't have to do any of detach_pid()'s.
Instead thread should change it's PID/TGID.
Am I wrong?
Kirill
