-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:
-rhel-2.4.21 RHEL3: 2.4.21-47.0.1.EL
-2.6-suse SLES9 before SP1 already in SLES9 SP1 kernel
-2.6-suse-newer SLES9: 2.6.5-7.282 extra patches for SLES9 after SP1
-2.6-rhel4 RHEL4: 2.6.9-42.0.8.EL
-2.6.12-vanilla kernel.org: 2.6.12.6
-2.6-sles10 SLES10: 2.6.16.21-0.8
+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.
-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.
+Servers running only ZFS OSDs DO NOT need any patches.
-NB - The patches in the ldiskfs series should not be applied to the kernel.
- They are instead applied by the lustre build process to create the
- ldiskfs kernel module instead of modifying the core ext3 code.
+Clients since 2.6.18 DO NOT need any patches.
-UNSUPPORTED KERNELS; BEING PHASED OUT; MAY BE MISSING CRITICAL BUG FIXES:
-hp-pnnl-2.4.20 linux-2.4.20-hp4_pnnl1 same as vanilla but no uml ia64
-vanilla-2.4.24 linux-2.4.24 patch with uml-2.4.24-6 um
+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
+
+See lustre/ChangeLog for supported client kernel versions.
