Freeze when coredump in unexistant directory in tmpfs

[Sébastien Marie]

Hi,

I run -current on amd64.

When a program generate a coredump in unexistant directory (cwd before
rmdir) in a tmpfs mount, my system freeze.

Under a tmpfs mount-point:

$ cat coreme.c
#include <stdlib.h>

int main()
{
        abort();
}

$ cc -o coreme coreme.c
$ mkdir testdir
$ cd testdir
$ D="${PWD%testdir}"
$ rmdir "$PWD"
$ $D/coreme
$ cd
### freeze ###

The freeze occurs only on tmpfs directory (ffs was tested, and seems not 
affected).

Thanks.
