Linux 2.6.20.21

[Willy Tarreau]

Hello,

I've just released Linux 2.6.20.21.

The following security issues are solved :
  CVE-2007-3104: store sysfs inode nrs in s_ino to avoid readdir oopses
  CVE-2007-4571: Convert snd-page-alloc proc file to use seq_file

A bunch of other fixes have been applied. No known vulnerability fix is
pending anymore.

I'll also be replying to this message with a copy of the patch between
2.6.20.20 and 2.6.20.21.

I'd like to repeat what I've already said several times: 2.6.20.21 is
the last 2.6.20.x release and there are no plans for any other one.
Upgrade to this one only as a quick temporary step towards a newer
major version.

The patch and changelog will appear soon at the following locations:
