[LU-12561] Remove RHEL6/SLES11 support from master for 2.13

• Type: Task
• Resolution: Fixed
• Priority: Blocker
• Fix Version/s: Lustre 2.13.0
• Affects Version/s: Lustre 2.13.0
• Assignee: Patrick Farrell (Inactive)
• Reporter: Andreas Dilger

Description

The master branch is no longer building for RHEL6.x kernels, so at a very minimum we shouldn't list RHEL 6.9 and 6.10 as "known to build" in lustre/ChangeLog and lustre/kernel_patches/which_patch for the 2.13 release, as this will otherwise lead to confusion. The same may be true of SLES11, but since it is a newer kernel version it may still build and should not be removed until after RHEL6 removal is finished.

To fully remove RHEL6.x/SLES11 support, several additional tasks are needed:

• remove kernel series files from lustre/kernel_patches/series and ldiskfs/kernel_patches/series/
• remove kernel patches from lustre/kernel_patches/patches/ and ldiskfs/kernel_patches/patches/ that are not used by later kernels
• remove libcfs/autoconf/, lnet/autoconf/, and lustre/autoconf/ checks for older kernels in kernel version order, starting with the oldest version and working toward the latest version that is still supported.

It is possible to use the contrib/scripts/clearpatches.sh script to verify which patches are unused after the series files are removed.
