From 066e825221012e1e81ccf46b0448772bdd7e5483 Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Tue, 12 Nov 2019 08:59:06 -0800 Subject: [PATCH] Linux compat: Minimum kernel version 3.10 Increase the minimum supported kernel version from 2.6.32 to 3.10. This removes support for the following Linux enterprise distributions. Distribution | Kernel | End of Life ---------------- | ------ | ------------- Ubuntu 12.04 LTS | 3.2 | Apr 28, 2017 SLES 11 | 3.0 | Mar 32, 2019 RHEL / CentOS 6 | 2.6.32 | Nov 30, 2020 The following changes were made as part of removing support. * Updated `configure` to enforce a minimum kernel version as specified in the META file (Linux-Minimum: 3.10). configure: error: *** Cannot build against kernel version 2.6.32. *** The minimum supported kernel version is 3.10. * Removed all `configure` kABI checks and matching C code for interfaces which solely predate the Linux 3.10 kernel. * Updated all `configure` kABI checks to fail when an interface is missing which was in the 3.10 kernel up to the latest 5.1 kernel. Removed the HAVE_* preprocessor defines for these checks and updated the code to unconditionally use the verified interface. * Inverted the detection logic in several kABI checks to match the new interface as it appears in 3.10 and newer and not the legacy interface. * Consolidated the following checks in to individual files. Due the large number of changes in the checks it made sense to handle this now. It would be desirable to group other related checks in the same fashion, but this as left as future work. - config/kernel-blkdev.m4 - Block device kABI checks - config/kernel-blk-queue.m4 - Block queue kABI checks - config/kernel-bio.m4 - Bio interface kABI checks * Removed the kABI checks for sops->nr_cached_objects() and sops->free_cached_objects(). These interfaces are currently unused.
