gfs-kmod bug fix update

Updated gfs-kmod packages which fix several issues are now available.

The gfs-kmod package contains kernel modules that provide the functionality
to mount and use GFS file systems.

These updated packages fixes the following bugs:

* using the lock_nolock protocol would still use locking methods
incorrectly. Locking methods are now disabled when the lock_nolock protocol
is in use.

* permission checks were handled in an incorrect way for SELinux.
Permission checks have been removed from xattr operations and moved to the
Virtual File System(VFS) layer which fixes this issue.

* the locking order in gfs_get_parent() was incorrect. The new modules use
the correct locking order.

* a bug with the locking protocol assertions would present as a file system
continuously being used by one resource, the file system being unavailable,
a 'fatal assertion "<=length"' message or, rarely, file system corruption.
The assertion bug that caused the errors mentioned has been fixed.

* a bug in gfs_quota could cause GFS to hang on large sparse files.
The gfs_quota tool now handles large sparse files more efficiently.

* a soft deadlock and kernel panic was caused by a NULL pointer difference
in gfs_glock_dq. This kernel panic has been fixed and the soft deadlock
should no longer occur.

* gfs_tool now recognizes GFS file systems on the PowerPC architecture.

Users are advised to upgrade to these latest gfs-kmod packages, which are
updated for use with Red Hat Enterprise Linux 5.

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

This update is available via Red Hat Network. Details on how to use
