Bug with linux-image-3 series

[Billy Nadeau <bill@mate1inc.com>]

Hello

hope this is a good place to send this...

calls to ulimit -n allow any user to raise it's limit once:

bill@river:~$ ulimit -n

1024

bill@river:~$ ulimit -n 4096 # Goes up once

bill@river:~$ ulimit -n 1024

bill@river:~$ ulimit -n 4096 # Not twice

-bash: ulimit: open files: cannot modify limit: Operation not permitted

bill@brook:~$ ulimit -n

1024

bill@brook:~$ ulimit -n 2048 # Goes up once

bill@brook:~$ ulimit -n

2048

bill@brook:~$ ulimit -n 4096 # Not twice

-su: ulimit: open files: cannot modify limit: Operation not permitted

bill@brook:~$ ulimit -n

2048

tested broken on the following kernels:

3.1.0-1-amd64

3.2.0-0.bpo.1-amd64

3.2.0-0.bpo.2-amd64

3.2.0-0.bpo.3-amd64

3.2.0-2-amd64

working normally on:

2.6.32-5-amd64

3.2.0-3-amd64

thanks
