Linux 2.6.23.14

Linux 2.6.23.14

[Greg Kroah-Hartman]

We (the -stable team) are announcing the release of the 2.6.23.14
kernel.

It contains a single fix for a problem that could cause a local user to
cause file system corruption on some types of filesystems.

All users of the 2.6.23 series are encouraged to upgrade.

I'll also be replying to this message with a copy of the patch between
2.6.23.13 and 2.6.23.14

The updated 2.6.23.y git tree can be found at:
        git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.23.y.git
and can be browsed at the normal kernel.org git web browser:
        http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.23.y.git;a=summary

thanks,

greg k-h
