-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: 2.6.16.60-0.39.3
-2.6-rhel5 RHEL5: 2.6.18-128.7.1.el5
-2.6-rhel5 OEL5: 2.6.18-128.7.1.el5
-2.6.18-vanilla kernel.org: 2.6.18.8
-2.6.22-vanilla kernel.org: 2.6.22.14
-2.6-sles11 SLES11: 2.6.27.23-0.1
+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 2.6.16-2.6.27
- 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.
