dlm-kernel bug-fix update

Updated dlm-kernel packages that fix various bugs and module-loading issues
are now available for Red Hat Enterprise Linux 4.8, kernel release
2.6.9-89.EL.

The dlm-kernel modules allow the Distributed Lock Manager (DLM) to
communicate with the kernel.

These updated packages apply the following bug fixes:

* A bug was fixed which could potentially cause a general protection fault
in dlm-kernel.

* The default lock_timeout of 30 seconds was increased to 2 minutes to
prevent userspace applications from failing when the load is very high.

* lockspaces are now forced to be null terminated.

* During an emergency shutdown dlm-kernel modules are now able to be unloaded.

Also, these updated dlm-kernel packages are in sync with the latest
kernel (2.6.9-89.EL). The modules in earlier dlm-kernel packages fail to
load because they do not match the running kernel. It is possible to
force-load the modules; however, with this update, force-loading the
modules is not required.

Users are advised to upgrade to these latest dlm-kernel packages, which are
updated for use with the 2.6.9-89.EL kernel.

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
