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(¤t->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?
