From 2b7bddf06c30da08f8d6270b40f0d382c1c5fc6e Mon Sep 17 00:00:00 2001 From: Jes Sorensen <jsorensen@fb.com> Date: Thu, 4 May 2017 11:39:05 -0400 Subject: [PATCH] kernel-patch: Remove obsolete kernel patches against 2.6 Git-commit: 2b7bddf06c30da08f8d6270b40f0d382c1c5fc6e Patch-mainline: mdadm-4.0+ References: bsc#1069165, bsc#1069167, bsc#1068030 While we still support some of these kernels, I do not think it makes sense to carry this patches around at this point.
