-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:
-2.6-rhel4             RHEL4: 2.6.9-67.0.20.EL
-2.6-sles10            SLES10: 2.6.16.60-0.31
-2.6-rhel5             RHEL5: 2.6.18-92.1.10.el5
-2.6.18-vanilla        kernel.org: 2.6.18.8
-2.6.22-vanilla        kernel.org: 2.6.22.14
+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.
 
-CLIENT SUPPORT FOR UNPATCHED KERNELS:
-                   kernel.org 2.6.16-2.6.22
-                   RHEL4: 2.6.9-42.0.8EL
+Servers running only ZFS OSDs DO NOT need any patches.
 
-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.
+Clients since 2.6.18 DO NOT need any patches.
