-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-suse              SLES9 before SP1         already in SLES9 SP1 kernel
-2.6-suse-newer        SLES9: 2.6.5-7.286       extra patches for SLES9 after SP1
-2.6-rhel4             RHEL4: 2.6.9-55.0.9.EL
-2.6-sles10            SLES10: 2.6.16.53-0.8
-2.6-rhel5.series      RHEL5: 2.6.18-8.1.14.el5
-2.6.18-vanilla.series kernel.org: 2.6.18.8
+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 2.6.16-2.6.19
-                   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.
+
+PATCH SERIES FOR SERVER KERNELS:
+2.6-rhel6.series       2.6.32-431.23.3.el6
+3.0-sles11sp3.series   3.0.101-0.31
