-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-rhel5             RHEL5: 2.6.18-238.19.1.el5
-2.6-rhel6             RHEL6: 2.6.32-220.17.1.el6
+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:
-         2.6.18-238.19.1.el5 (RHEL5)

+Servers running only ZFS OSDs DO NOT need any patches.
