Subject: Core dumps for threads
Date: Sat, 24 Feb 2001 13:45:23 -0800	[thread overview]
Message-ID: <20010224134523.O26109@valinux.com> (raw)

Can anyone explain why this test is in routine `do_coredump'
in file `fs/exec.c' in the 2.4.0 kernel?

    if (!current->dumpable || atomic_read(&current->mm->mm_users) != 1)
	goto fail;

The only thing the test on `mm_users' seems to be doing is stopping
a thread process from dumping core.  What's the rationale for this?
