From 928046b744a6d3f93f5ba1351a6d700a62535a00 Mon Sep 17 00:00:00 2001 From: Antonio Russo Date: Wed, 30 May 2018 23:11:19 -0400 Subject: [PATCH] Explicitly state supported Linux versions Add META tags Linux-Maximum and Linux-Minimum. One pain point for package maintainers is ensuring the compatibility of the packaged version of ZFS with the Linux kernel. By providing an authoritative compatibility guide in the source tree, maintainers can automate compatibility checks. Additionally, increase META string extraction specificity. configure.ac finds Name and Version by a very simple `grep`, which might conceivably find other fields. Require the string be at the beginning of a line, and be followed by a colon to avoid such confusions.
