Linux 2.6.27.38

Linux 2.6.27.38

[Greg KH]

I'm announcing the release of the 2.6.27.38 kernel.  All users of the
2.6.27 kernel series that use SCSI devices, or USB to serial devices are
very strongly encouraged to upgrade.

The updated 2.6.27.y git tree can be found at:
        git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.27.y.git
and can be browsed at the normal kernel.org git web browser:
        http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.27.y.git;a=summary

thanks,

greg k-h
