Subject: question about fork_main()
Date: Thu, 09 Apr 2009 20:49:10 +0200	[thread overview]
Message-ID: <m2eiw1fys9.fsf@gmail.com> (raw)

hello,

I just took a look to fio source code (great tool BTW), and I'm
wondering about the fork_main() comment:

/*
 * We cannot pass the td data into a forked process, so attach the td
 * and pass it to the thread worker.
 */

Since after a fork(2) the child inherits the attached shared memory
segments from its parent, I don't see the point of this comment.

Could anybody enlight me ?

thanks.
