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

• Status: Resolved

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.

It looks like after the RHEL6 kernel patch series are removed the patches that are no longer needed as reported by clearpatches.sh are:

Unused raid5-mmp-unplug-dev-rhel6.patch
Unused blkdev_tunables-3.8.patch
Unused quota-replace-dqptr-sem.patch
Unused jbd2-fix-j_list_lock-unlock-3.10-rhel7.patch
Unused dev_read_only-2.6.32-sles11.patch

James, if you have a chance to review these, they're more 2.6/RHEL6 removal related stuff.
