-SERIES             VERSION                  COMMENT
+Note that Lustre server kernels do not REQUIRE patches to the core kernel
+code in order to function.  However, the server kernel patches may improve
+performance significantly.  Lustre may not work with the latest kernels
+due to API changes in the kernel.  See lustre/ChangeLog for details.
 
-SUPPORTED KERNELS:
-rhel-2.4.21        RHEL3: 2.4.21-47.0.1.EL
-2.6-suse           SLES9 before SP1         already in SLES9 SP1 kernel
-2.6-suse-newer     SLES9: 2.6.5-7.282       extra patches for SLES9 after SP1
-2.6-rhel4          RHEL4: 2.6.9-42.0.3.EL
-2.6.12-vanilla     kernel.org: 2.6.12.6
+In addition to the patches that should be applied to the core kernel,
+patches are required for a specific kernel in order to build the ldiskfs
+module from ext4.  Those patches are applied automatically during the
+ldiskfs build process and SHOULD NOT be applied to the kernel directly.
 
-NB - The patches in the 2.6-suse series should already be in the SLES9 SP1
-     kernel.  The patches in the 2.6-suse-newer series are patches that
-     have been created since the SP1 kernel was released and should be
-     applied to the already-patched SP1 kernel.
+Servers running only ZFS OSDs DO NOT need any patches.
 
-NB - The patches in the ldiskfs series should not be applied to the kernel.
-     They are instead applied by the lustre build process to create the
-     ldiskfs kernel module instead of modifying the core ext3 code.
+Clients since 2.6.18 DO NOT need any patches.
