+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.
+
+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.
+
+Servers running only ZFS OSDs DO NOT need any patches.
+
+Clients since 2.6.18 DO NOT need any patches.
